FIELD OF THE INVENTION

This invention provides substituted acylanilide compounds and uses thereof in treating a variety of diseases or conditions in a subject, including, inter alia, a muscle wasting disease and/or disorder such as muscular dystrophies including Duchenne muscular dystrophy and Becker muscular dystrophy.

BACKGROUND OF THE INVENTION

Muscle wasting refers to the progressive loss of muscle mass and/or to the progressive weakening and degeneration of muscles, including the skeletal or voluntary muscles, which control movement, cardiac muscles, which control the heart (cardiomyopathies), and smooth muscles. Chronic muscle wasting is a chronic condition (i.e. persisting over a long period of time) characterized by progressive loss of muscle mass, and weakening and degeneration of muscle.

The loss of muscle mass that occurs during muscle wasting can be characterized by muscle protein degradation by catabolism. Protein catabolism occurs because of an unusually high rate of protein degradation, an unusually low rate of protein synthesis, or a combination of both. Muscle protein catabolism, whether caused by a high degree of protein degradation or a low degree of protein synthesis, leads to a decrease in muscle mass and to muscle wasting.

Muscle wasting is associated with chronic, neurological, genetic or infectious pathologies, diseases, illnesses or conditions. These include muscular dystrophies such as Duchenne muscular dystrophy, Becker muscular dystrophy, limb-girdle disease, and myotonic dystrophy; muscle atrophies such as post-polio muscle atrophy (PPMA); cachexias such as cardiac cachexia, AIDS cachexia and cancer cachexia; and malnutrition, leprosy, diabetes, renal disease, chronic obstructive pulmonary disease (COPD), cancer, end stage renal failure, sarcopenia, emphysema, osteomalacia, HIV infection, AIDS, and cardiomyopathy.

In addition, other circumstances and conditions are linked to and can cause muscle wasting. These include chronic lower back pain, advanced age, central nervous system (CNS) injury, peripheral nerve injury, spinal cord injury, chemical injury, central nervous system (CNS) damage, peripheral nerve damage, spinal cord damage, chemical damage, burns, disuse deconditioning that occurs when a limb is immobilized, long term hospitalization due to illness or injury, and alcoholism.

An intact androgen receptor (AR) signaling pathway is crucial for appropriate development of skeletal muscles. Furthermore, an intact AR-signaling pathway increases lean muscle mass, muscle strength and muscle protein synthesis.

Muscle wasting, if left unabated, can have dire health consequences. For example, the changes that occur during muscle wasting can lead to a weakened physical state that is detrimental to an individual's health, resulting in increased susceptibility to bone fracture and poor physical performance status. In addition, muscle wasting is a strong predictor of morbidity and mortality in patients suffering from cachexia and AIDS.

Duchenne muscular dystrophy is the most common of nine muscular dystrophies and occurs in 1/3500 to 1/5000 males around the world. Duchenne muscular dystrophy patients experience difficulty with walking at 3-5 years of age, progressive worsening of symptoms, and death in the teens to 3^(rd) decade. Discovered in the 1860's, little was known about the pathogenesis of Duchenne muscular dystrophy until 1986 when the gene underlying this X-linked autosomal recessive disease was cloned and characterized. The gene was named dystrophin (DMD) and found to be part of a sarcolemma (i.e. myocte plasma membrane) protein complex (dystrophin-glycoprotein complex) which connects the myofibril (muscle cell) cytoskeleton to the extracellular matrix, thereby protecting the muscle cell membrane from physical trauma during muscle exertion and exercise. Duchenne muscular dystrophy is predominantly a disease in males and is associated with a variety of mutations of the DMD gene which leads to a wide variation of disease severities. Sarcolemma fragility produces progressive calcium permeability, protease activation, oxidative stress, and inflammation which causes progressive replacement of muscle cells by fibrous tissue and/or conversion to fat. Gross pathology includes weakness and degeneration of skeletal and voluntary muscle which is exacerbated by high impact exercise, muscle contractures that worsen mobility if not corrected, and scoliosis. Although braces and walkers provide some protection, declines in physical function result in loss of ambulation during childhood leading to wheelchair confinement, and eventually impaired cardiac (cardiomyopathy) or respiratory (diaphragm fibrosis) function leads to death. Average life expectancy has improved (and rare cases of men living into their 4^(th) or 5^(th) decade) as a result of better respiratory (glucocorticoids) and cardiac (ACE inhibitors, angiotensin receptor blockers, and beta-blockers) supportive care but no disease-modifying therapeutics exist. Anabolics (steroidal androgens, IGF-I, etc.) to slow the rate of physical function decline have been proposed and were shown to provide some benefit in small clinical trials, but no nonsteroidal or tissue-selective androgen receptor modulator (SARM) has entered clinical testing for Duchenne muscular dystrophy. The loss of gene function etiology has attracted great interest toward gene therapy approaches to treat the disease; however, such treatments have not completely reversed the phenotype and suffer from difficulties inherent in nucleotide polymer based therapeutics which are exacerbated by the large and complex nature of the dystrophin gene. The above suggests that other therapeutic targets are urgently needed. Consequently, there is increasing interest in further improving the quality of life and length of life via symptom directed supportive care. Aryl propanamide SARMs have been shown to increase global anabolic tone in multiple clinical trials through increases in muscle mass (lean body mass by DEXA) and physical function (e.g., leg press, grip strength, stair climb power) suggesting that they may have therapeutic effects on dystrophic skeletal and specifically diaphragm muscle, cardiac, and smooth muscle, or may delay onset or improve symptoms of loss of mobility/autonomy, cardiomyopathy, or respiratory insufficiency in Duchenne muscular dystrophy or Becker muscular dystrophy and other muscular dystrophy patients.

Becker muscular dystrophy is a rarer and milder variation of Duchenne muscular dystrophy caused by DMD mutants that do not completely abrogate dystrophin glycoprotein complex function in males or more commonly it is observed in some female carriers (Duchenne muscular dystrophy is often asymptomatic in females). Becker muscular dystrophy has a phenotype with less functional impairment and longer life expectancy, but clinical cardiomyopathies and respiratory insufficiencies must be closely monitored.

Interest in drug design for Duchenne muscular dystrophy was hampered by the lack of good models of this disease, however several in vivo disease models now exist. These include the dystrophin gene deletion in mice (mdx mice; denoted by DMD (−/−)) which presents a phenotype representative of the early stages of the disease in humans however, is not progressive in symptomology and much less severe in the later stages of the disease. Double-knockout (knock-down) mice lacking dystrophin (DMD) and utrophin (UTRN, a protein that can partially compensate for lack of dystrophin) (i.e., DMD (−/−) UTRN (−/−)) present a phenotype more representative of the natural history of Duchenne muscular dystrophy in humans including progressive worsening of symptoms, loss of ambulation at ˜12 weeks, and early death by ˜20 weeks. [A severe phenotype can also be derived from the mdx model by forced treadmill running.] Golden retriever muscular dystrophy is another disease model that matches the human phenotype in some ways but suffers from a high level of interindividual variation even among littermates, complicating the interpretation of results. Although the pathogenesis of other muscular dystrophies is not related to Duchenne and Becker muscular dystrophies, the phenotypes therein suggest that activity in the mdx and double knockout models may be indicative of therapeutic efficacies in those disease states as well.

While there are many treatments and therapies for these conditions, none are ideal. Since the androgen receptor (AR) signaling pathway has been shown to increase lean muscle mass, muscle strength and muscle protein synthesis, and since hypogonadism accompanies these conditions, molecules targeting the AR signaling pathway may be useful in treating these diseases and/or conditions.

Further, in another embodiment, the pharmaceutical compositions are administered by subcutaneous implantation of a pellet. In a further embodiment, the pellet provides for controlled release of SARM agent over a period of time. In a further embodiment, the pharmaceutical compositions are administered intravaginally.

In another embodiment, the active compound can be delivered in a vesicle, in particular a liposome (see Langer, Science 249:1527-1533 (1990); Treat et al., in Liposomes in the Therapy of Infectious Disease and Cancer, Lopez-Berestein and Fidler (eds.), Liss, New York, pp. 353-365 (1989); Lopez-Berestein, ibid., pp. 317-327; see generally ibid).

As used herein “pharmaceutically acceptable carriers or diluents” are well known to those skilled in the art. The carrier or diluent may be a solid carrier or diluent for solid formuations, a liquid carrier or diluent for liquid formulations, or mixtures thereof.

Solid carriers/diluents include, but are not limited to, a gum, a starch (e.g. corn starch, pregeletanized starch), a sugar (e.g., lactose, mannitol, sucrose, dextrose), a cellulosic material (e.g. microcrystalline cellulose), an acrylate (e.g. polymethylacrylate), calcium carbonate, magnesium oxide, talc, or mixtures thereof.

In one embodiment, the compositions of this invention may include, a SARM of this invention or any combination thereof, together with one or more pharmaceutically acceptable excipients.

Suitable excipients and carriers may be, according to embodiments of the invention, solid or liquid and the type is generally chosen based on the type of administration being used. Liposomes may also be used to deliver the composition. Examples of suitable solid carriers include lactose, sucrose, gelatin and agar. Oral dosage forms may contain suitable binders, lubricants, diluents, disintegrating agents, coloring agents, flavoring agents, flow-inducing agents, and melting agents. Liquid dosage forms may contain, for example, suitable solvents, preservatives, emulsifying agents, suspending agents, diluents, sweeteners, thickeners, and melting agents. Parenteral and intravenous forms should also include minerals and other materials to make them compatible with the type of injection or delivery system chosen. Of course, other excipients may also be used.

For liquid formulations, pharmaceutically acceptable carriers may be aqueous or non-aqueous solutions, suspensions, emulsions or oils. Examples of non-aqueous solvents are propylene glycol, polyethylene glycol, and injectable organic esters such as ethyl oleate. Aqueous carriers include water, alcoholic/aqueous solutions, cyclodextrins, emulsions or suspensions, including saline and buffered media. Examples of oils are those of petroleum, animal, vegetable, or synthetic origin, for example, peanut oil, soybean oil, mineral oil, olive oil, sunflower oil, and fish-liver oil.

Parenteral vehicles (for subcutaneous, intravenous, intraarterial, or intramuscular injection) include sodium chloride solution, Ringer's dextrose, dextrose and sodium chloride, lactated Ringer's and fixed oils. Intravenous vehicles include fluid and nutrient replenishers, electrolyte replenishers such as those based on Ringer's dextrose, and the like. Examples are sterile liquids such as water and oils, with or without the addition of a surfactant and other pharmaceutically acceptable adjuvants. In general, water, saline, aqueous dextrose and related sugar solutions, and glycols such as propylene glycols or polyethylene glycol are preferred liquid carriers, particularly for injectable solutions. Examples of oils are those of petroleum, animal, vegetable, or synthetic origin, for example, peanut oil, soybean oil, mineral oil, olive oil, sunflower oil, and fish-liver oil.

In addition, the compositions may further comprise binders (e.g. acacia, cornstarch, gelatin, carbomer, ethyl cellulose, guar gum, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, povidone), disintegrating agents (e.g. cornstarch, potato starch, alginic acid, silicon dioxide, croscarmellose sodium, crospovidone, guar gum, sodium starch glycolate), buffers (e.g., Tris-HCl, acetate, phosphate) of various pH and ionic strength, additives such as albumin or gelatin to prevent absorption to surfaces, detergents (e.g., Tween® 20, Tween® 80, Pluronic F68®, bile acid salts), protease inhibitors, surfactants (e.g. sodium lauryl sulfate), permeation enhancers, solubilizing agents (e.g., Cremophor®, glycerol, polyethylene glycerol, benzlkonium chloride, benzyl benzoate, cyclodextrins, sobitan esters, stearic acids), anti-oxidants (e.g., ascorbic acid, sodium metabisulfite, butylated hydroxyanisole), stabilizers (e.g. hydroxypropyl cellulose, hyroxypropylmethyl cellulose), viscosity increasing agents (e.g. carbomer, colloidal silicon dioxide, ethyl cellulose, guar gum), sweetners (e.g. aspartame, citric acid), preservatives (e.g., Thimerosal®, benzyl alcohol, parabens), coloring agents, lubricants (e.g. stearic acid, magnesium stearate, polyethylene glycol, sodium lauryl sulfate), flow-aids (e.g. colloidal silicon dioxide), plasticizers (e.g. diethyl phthalate, triethyl citrate), emulsifiers (e.g. carbomer, hydroxypropyl cellulose, sodium lauryl sulfate), polymer coatings (e.g., poloxamers or poloxamines), coating and film forming agents (e.g. ethyl cellulose, acrylates, polymethacrylates), and/or adjuvants.

In one embodiment, the pharmaceutical compositions provided herein are controlled release compositions, i.e. compositions in which the SARM compound is released over a period of time after administration. Controlled or sustained release compositions include formulation in lipophilic depots (e.g. fatty acids, waxes, oils). In another embodiment, the composition is an immediate release composition, i.e. a composition in which all of the SARM compound is released immediately after administration.

In another embodiment, the pharmaceutical composition can be delivered in a controlled release system. For example, the agent may be administered using intravenous infusion, an implantable osmotic pump, a transdermal patch, liposomes, or other modes of administration. In one embodiment, a pump may be used (see Langer, supra; Sefton, CRC Crit. Ref. Biomed. Eng. 14:201 (1987); Buchwald et al., Surgery 88:507 (1980); Saudek et al., N. Engl. J. Med. 321:574 (1989). In another embodiment, polymeric materials can be used. In yet another embodiment, a controlled release system can be placed in proximity to the therapeutic target, i.e., the brain, thus requiring only a fraction of the systemic dose (see, e.g., Goodson, in Medical Applications of Controlled Release, supra, vol. 2, pp. 115-138 (1984). Other controlled release systems are discussed in the review by Langer (Science 249:1527-1533 (1990).

The compositions may also include incorporation of the active material into or onto particulate preparations of polymeric compounds such as polylactic acid, polglycolic acid, hydrogels, etc, or onto liposomes, microemulsions, micelles, unilamellar or multilamellar vesicles, erythrocyte ghosts, or spheroplasts. Such compositions will influence the physical state, solubility, stability, rate of in vivo release, and rate of in vivo clearance.

Also comprehended by the invention are particulate compositions coated with polymers (e.g. poloxamers or poloxamines) and the compound coupled to antibodies directed against tissue-specific receptors, ligands or antigens or coupled to ligands of tissue-specific receptors.

Also comprehended by the invention are compounds modified by the covalent attachment of water-soluble polymers such as polyethylene glycol, copolymers of polyethylene glycol and polypropylene glycol, carboxymethyl cellulose, dextran, polyvinyl alcohol, polyvinylpyrrolidone or polyproline. The modified compounds are known to exhibit substantially longer half-lives in blood following intravenous injection than do the corresponding unmodified compounds (Abuchowski et al., 1981; Newmark et al., 1982; and Katre et al., 1987). Such modifications may also increase the compound's solubility in aqueous solution, eliminate aggregation, enhance the physical and chemical stability of the compound, and greatly reduce the immunogenicity and reactivity of the compound. As a result, the desired in vivo biological activity may be achieved by the administration of such polymer-compound abducts less frequently or in lower doses than with the unmodified compound.

The preparation of pharmaceutical compositions, which contain an active component is well understood in the art, for example by mixing, granulating, or tablet-forming processes. The active therapeutic ingredient is often mixed with excipients which are pharmaceutically acceptable and compatible with the active ingredient. For oral administration, the SARM agents or their physiologically tolerated derivatives such as salts, esters, N-oxides, and the like are mixed with additives customary for this purpose, such as vehicles, stabilizers, or inert diluents, and converted by customary methods into suitable forms for administration, such as tablets, coated tablets, hard or soft gelatin capsules, aqueous, alcoholic or oily solutions. For parenteral administration, the SARM agents or their physiologically tolerated derivatives such as salts, esters, N-oxides, and the like are converted into a solution, suspension, or emulsion, if desired with the substances customary and suitable for this purpose, for example, solubilizers or other.

An active component can be formulated into the composition as neutralized pharmaceutically acceptable salt forms. Pharmaceutically acceptable salts include the acid addition salts (formed with the free amino groups of the polypeptide or antibody molecule), which are formed with inorganic acids such as, for example, hydrochloric or phosphoric acids, or such organic acids as acetic, oxalic, tartaric, mandelic, and the like. Salts formed from the free carboxyl groups can also be derived from inorganic bases such as, for example, sodium, potassium, ammonium, calcium, or ferric hydroxides, and such organic bases as isopropylamine, trimethylamine, 2-ethylamino ethanol, histidine, procaine, and the like.

For use in medicine, the salts of the compounds of formula I-XX and S-(III) will be pharmaceutically acceptable salts. Other salts may, however, be useful in the preparation of the compounds according to the invention or of their pharmaceutically acceptable salts. Suitable pharmaceutically acceptable salts of the compounds of this invention include acid addition salts which may, for example, be formed by mixing a solution of the compound according to the invention with a solution of a pharmaceutically acceptable acid such as hydrochloric acid, sulphuric acid, methanesulphonic acid, fumaric acid, maleic acid, succinic acid, acetic acid, benzoic acid, oxalic acid, citric acid, tartaric acid, carbonic acid or phosphoric acid.

In one embodiment, this invention provides compounds, compositions and/or methods of use thereof in treating benign prostate hyperplasia (BPH). “BPH (benign prostate hyperplasia)” is a nonmalignant enlargement of the prostate gland, and is the most common nonmalignant proliferative abnormality found in any internal organ and the major cause of morbidity in the adult male. BPH occurs in over 75% of men over 50 years of age, reaching 88% prevalence by the ninth decade. BPH frequently results in a gradual squeezing of the portion of the urethra which traverses the prostate (prostatic urethra). This causes patients to experience a frequent urge to urinate because of incomplete emptying of the bladder and urgency of urination. The obstruction of urinary flow can also lead to a general lack of control over urination, including difficulty initiating urination when desired, as well as difficulty in preventing urinary flow because of the inability to empty urine from the bladder, a condition known as overflow urinary incontinence, which can lead to urinary obstruction and to urinary failure.

In another embodiment of the present invention, the method for treating benign prostate hyperplasia (BPH) in a subject, comprises the step of administering to the subject a SARM compound as herein described and/or its analog, derivative, isomer, metabolite, pharmaceutically acceptable salt, pharmaceutical product, polymorph, crystal, impurity, hydrate, N-oxide or any combination thereof, in an amount effective to treat BPH in the subject.

In another embodiment, the administering step includes intravenously, intraarterially, or intramuscularly injecting to said subject said pharmaceutical composition in liquid form; subcutaneously implanting in said subject a pellet containing said pharmaceutical composition; orally administering to said subject said pharmaceutical composition in a liquid or solid form; or topically applying to the skin surface of said subject said pharmaceutical composition.

A muscle is a tissue of the body that primarily functions as a source of power. There are three types of muscles in the body: a) skeletal muscle—the muscle responsible for moving extremities and external areas of the bodies; b) cardiac muscle—the heart muscle; and c) smooth muscle—the muscle that is in the walls of arteries and bowel.

A wasting condition or disorder is defined herein as a condition or disorder that is characterized, at least in part, by an abnormal, progressive loss of body, organ or tissue mass. A wasting condition can occur as a result of a pathology such as, for example, cancer, or an infection, or it can be due to a physiologic or metabolic state, such as disuse deconditioning that can occur, for example, due to prolonged bed rest or when a limb is immobilized, such as in a cast. A wasting condition can also be age associated. The loss of body mass that occurs during a wasting condition can be characterized by a loss of total body weight, or a loss of organ weight such as a loss of bone or muscle mass due to a decrease in tissue protein.

In one embodiment, the terms “muscle wasting” or “muscular wasting”, used herein interchangeably, refer to the progressive loss of muscle mass and/or to the progressive weakening and degeneration of muscles, including the skeletal or voluntary muscles which control movement, cardiac muscles which control the heart, and smooth muscles. In one embodiment, the muscle wasting condition or disorder is a chronic muscle wasting condition or disorder. “Chronic muscle wasting” is defined herein as the chronic (i.e. persisting over a long period of time) progressive loss of muscle mass and/or to the chronic progressive weakening and degeneration of muscle.

The term cachexia may be defined as a multifactorial syndrome characterized by severe body weight, fat and muscle loss and increased protein catabolism due to underlying disease(s). Cachexia is clinically relevant since it increases patients' morbidity and mortality. Contributory factors to the onset of cachexia are anorexia and metabolic alterations, i.e. increased inflammatory status, increased muscle proteolysis, impaired carbohydrate, protein and lipid metabolism

“Pre-cachexia” or “early cachexia” are defined based on the presence of some or all of the following criteria: (a) underlying chronic disease; (b) unintentional weight loss <5% of usual body weight during the last 6 months; (c) chronic or recurrent systemic inflammatory response; and (d) anorexia or anorexia-related symptoms. Pre-cachexia or early cachexia may include therefore patients with a chronic disease, small weight loss, and a chronic or recurrent systemic inflammatory disease and/or anorexia

Muscle wasting can occur as a result of pathology, disease, condition or disorders, including disorders for treatment via the methods of this invention, such as, for example, end stage renal failure.

The loss of muscle mass that occurs during muscle wasting can be characterized by a muscle protein breakdown or degradation, or by muscle protein catabolism. Protein catabolism occurs because of an unusually high rate of protein degradation, an unusually low rate of protein synthesis, or a combination of both. Protein catabolism or depletion, whether caused by a high degree of protein degradation or a low degree of protein synthesis, leads to a decrease in muscle mass and to muscle wasting. The term “catabolism” has its commonly known meaning in the art, specifically an energy burning form of metabolism.

Muscle wasting can occur as a result of a pathology, disease, condition or disorder. In one embodiment, the pathology, illness, disease or condition is chronic. In another embodiment, the pathology, illness, disease or condition is genetic. In another embodiment, the pathology, illness, disease or condition is neurological. In another embodiment, the pathology, illness, disease or condition is infectious. As described herein, the pathologies, diseases, conditions or disorders for which the compounds and compositions of the present invention are administered are those that directly or indirectly produce a wasting (i.e. loss) of muscle mass, that is a muscle wasting disorder.

In one embodiment, muscle wasting in a subject is a result of the subject having a muscular dystrophy, muscle atrophy, or X-linked spinal-bulbar muscular atrophy (SBMA).

In some embodiments, muscle loss or muscle wasting or cachexia in a subject results in reduced protein reserves, decreased strength and functional capacity, frailty, falls, reduced aerobic capacity, reduced energy requirements or increased mortality in patients and the methods of this invention serve to treat these conditions, as well, in the subject, via the administration of any embodiment of a SARM and/or composition as described herein.

In some embodiments, muscle loss or muscle wasting or cachexia in a subject results in increased dietary protein needs, inflammation (accelerated muscle protein breakdown), loss of motor units (aging CNS), reduced rate of muscle protein synthesis (post-prandial), and/or changing endocrine function (testosterone, estrogen, growth hormone, insulin resistance) and the methods of this invention serve to treat these conditions, as well, in the subject, via the administration of any embodiment of a SARM and/or composition as described herein.

In some embodiments, this invention provides methods for the treating of sarcopenia and/or cachexia, via the administration of any embodiment of a compound and/or composition as described herein.

In some embodiments, treatment with a compound and/or composition as described herein may provide for the increased rate of muscle protein synthesis, increased muscle size and strength, improved functional status in elderly people, increased independence for older, frail people, increased insulin sensitivity, which in some embodiments is whereby such administration results in the treatment of cachexia and/or sarcopenia or other disorders as described herein. Muscle is the primary site for glucose metabolism, insulin resistance is largely a problem of resistance of muscle to insulin, resulting from increased lipid in muscle cells, increased total fat, increased visceral fat, with the compounds and/or compositions of this invention being useful to reduce total fat, thereby increasing insulin sensitivity and/or reducing the risk of, or treating, etc., diabetes, as described herein.

The muscular dystrophies are genetic diseases characterized by progressive weakness and degeneration of the skeletal or voluntary muscles that control movement. The muscles of the heart and some other involuntary muscles are also affected in some forms of muscular dystrophy. The nine forms of muscular dystrophy (MD) are: myotonic dystrophy, Duchenne muscular dystrophy, Becker muscular dystrophy, limb-girdle muscular dystrophy, facioscapulhumeral muscular dystrophy, congenital muscular dystrophy, oculopharyngeal muscular dystrophy, distal muscular dystrophy and Emery-Dreifuss muscular dystrophy.

Muscular dystrophy can affect people of all ages. Although some forms first become apparent in infancy or childhood, others may not appear until middle age or later. Myotonic dystrophy is the most common of these diseases in adults. Myotonic dystrophy is an autosomal dominant genetic disease that occurs in 1/8000 people and is characterized by 2 types. Type I has a genetic defect in the DMPK gene whereas type II has a genetic defect in the CNBP gene. The mutation is an abnormal repeat of a DNA segment which presents a disease phenotype of variable severity in the 2^(nd) or 3^(rd) decade of life. Symptoms of the disease may include inter alia prolonged contractions (myotonia) of certain muscles, cataracts, cardiac conduction defects, balding, or male infertility.

Duchenne MD is the most common form, typically affecting children. Duchenne muscular dystrophy includes weakness and degeneration of skeletal and voluntary muscle which is exacerbated by high impact exercise, muscle contractures that worsen mobility if not corrected, and scoliosis. Although braces and walkers provide some protection, declines in physical function result in loss of ambulation during childhood leading to wheelchair confinement, and eventually impaired cardiac (cardiomyopathy) or respiratory (diaphragm fibrosis) function leads to death. Average life expentancy has improved (and rare cases of men living into their 4^(th) or 5^(th) decade) as a result of better respiratory (glucocorticoids) and cardiac (ACE inhibitors, angiotensin receptor blockers, and beta-blockers) supportive care but no disease-modifying therapeutics exist.

Becker muscular dystrophy is a rarer and milder variation of Duchenne muscular dystrophy caused by DMD mutants that do not completely abrogate dystrophin glycoprotein complex function in males or more commonly is observed in some female carriers (Duchenne muscular dystrophy is often asymptomatic in females).

In one embodiment, this invention provides therapeutic effects on dystrophic skeletal, cardiac, and diaphragm muscles, or may delay onset or improve symptoms of loss of mobility/autonomy, cardiomyopathy, or respiratory insufficiency in Duchenne muscular dystrophy or Becker muscular dystrophy and other muscular dystrophy patients; by administering the compound of this invention.

Muscle atrophy (MA) is characterized by wasting away or diminution of muscle and a decrease in muscle mass. For example, post-polio MA is a muscle wasting that occurs as part of the post-polio syndrome (PPS). The atrophy includes weakness, muscle fatigue, and pain.

Another type of MA is X-linked spinal-bulbar muscular atrophy (SBMA—also known as Kennedy's Disease). This disease arises from a defect in the androgen receptor gene on the X chromosome, affects only males, and its onset is in adulthood. Because the primary disease cause is an androgen receptor mutation, androgen replacement is not a current therapeutic strategy. There are some investigational studies where exogenous testosterone propionate is being given to boost the levels of androgen with hopes of overcoming androgen insensitivity and perhaps provide an anabolic effect. Still, use of supraphysiological levels of testosterone for supplementation will have limitations and other potentially serious complications.

In one embodiment, this invention is directed to a method of treating, reducing the severity, reducing the incidence, delaying the onset, or reducing the pathogenesis of Duchenne muscular dystrophy in a subject in need thereof, comprising the step of administering to said subject a selective androgen receptor modulator (SARM) compound represented by the structure of formula S-(III):

Sarcopenia is a debilitating disease that afflicts the elderly and chronically ill patients and is characterized by loss of muscle mass and function. Further, increased lean body mass is associated with decreased morbidity and mortality for certain muscle-wasting disorders. In addition, other circumstances and conditions are linked to, and can cause muscle wasting disorders. For example, studies have shown that in severe cases of chronic lower back pain, there is paraspinal muscle wasting.

Muscle wasting and other tissue wasting is also associated with advanced age. It is believed that general weakness in old age is due to muscle wasting. As the body ages, an increasing proportion of skeletal muscle is replaced by fibrous tissue. The result is a significant reduction in muscle power, performance and endurance.

Long term hospitalization due to illness or injury, or disuse deconditioning that occurs, for example, when a limb is immobilized, can also lead to muscle wasting, or wasting of other tissue. Studies have shown that in patients suffering injuries, chronic illnesses, burns, trauma or cancer, who are hospitalized for long periods of time, there is a long-lasting unilateral muscle wasting, and a decrease in body mass.

Injuries or damage to the central nervous system (CNS) are also associated with muscle wasting and other wasting disorders. Injuries or damage to the CNS can be, for example, caused by diseases, trauma or chemicals. Examples are central nerve injury or damage, peripheral nerve injury or damage and spinal cord injury or damage. In one embodiment CNS damage or injury comprise Alzheimer's diseases (AD), anger (mood), anorexia, anorexia nervosa, anorexia associated with aging and/or assertiveness (mood).

In another embodiment, muscle wasting or other tissue wasting may be a result of alcoholism, and may be treated with the compounds and compositions of the invention, representing embodiments thereof.

In one embodiment, the invention provides a use of SARM compound as described herein or its prodrug, analog, isomer, metabolite, derivative, pharmaceutically acceptable salt, pharmaceutical product, polymorph, crystal, impurity, N-oxide, hydrate or any combination thereof for the treatment of a wasting disease, disorder or condition in a subject.

In one embodiment, the wasting disease, disorder or condition being treated is associated with chronic illness

This invention is directed to treating, in some embodiments, any wasting disorder, which may be reflected in muscle wasting, weight loss, malnutrition, starvation, or any wasting or loss of functioning due to a loss of tissue mass.

In some embodiments, wasting diseases or disorders, such as cachexia, malnutrition, tuberculosis, leprosy, diabetes, renal disease, chronic obstructive pulmonary disease (COPD), cancer, end stage renal failure, sarcopenia, emphysema, osteomalacia, or cardiomyopathy, may be treated by the methods of this invention, via the administration of a SARM compound as herein described, compositions comprising the same, with or without additional drugs, compounds, or agents, which provide a therapeutic effect for the condition being treated.

In some embodiments, wasting is due to infection with enterovirus, Epstein-Barr virus, herpes zoster, HIV, trypanosomes, influenza, coxsackie, rickettsia, trichinella, schistosoma or mycobacteria, and this invention, in some embodiments, provides methods of treatment thereof.

Cachexia is weakness and a loss of weight caused by a disease or as a side effect of illness. Cardiac cachexia, i.e. a muscle protein wasting of both the cardiac and skeletal muscle, is a characteristic of congestive heart failure. Cancer cachexia is a syndrome that occurs in patients with solid tumors and hematological malignancies and is manifested by weight loss with massive depletion of both adipose tissue and lean muscle mass.

Cachexia is also seen in acquired immunodeficiency syndrome (AIDS), human immunodeficiency virus (HIV)-associated myopathy and/or muscle weakness/wasting is a relatively common clinical manifestation of AIDS. Individuals with HIV-associated myopathy or muscle weakness or wasting typically experience significant weight loss, generalized or proximal muscle weakness, tenderness, and muscle atrophy.

In some embodiments, cranial nerve diseases comprise bell palsy, cranial nerve diseases, facial hemiatrophy, facial neuralgia, glossopharyngeal nerve diseases, Moebius syndrome, or trigeminal neuralgia.

In some embodiments, central nervous system diseases comprise injuries or damage to the central nervous system (CNS). In some embodiments, injuries or damage to the CNS may be associated with muscle wasting disorders. Injuries or damage to the CNS can be, for example, caused by diseases, trauma or chemicals. Examples are central nerve injury or damage, peripheral nerve injury or damage and spinal cord injury or damage.

Studies involving patients with spinal cord injuries (SCI) have shown that central neurotransmitters may be altered after SCI causing hypothalamus-pituitary-adrenal axis dysfunction, whose disruption led to a significant decrease in testosterone and other hormone levels. SCI or other acute illness or trauma characteristically includes heightened catabolism in conjunction with the lowered anabolic activity resulting in a condition that is prone to loss of lean body tissue, which is often accompanied by disturbed nutrient utilization. The effects of the loss of lean body mass include the development of wounds and impaired healing mechanisms, further compounding the problem. Because of poor nutrition and protein combined with immobilization, patients with spinal cord injury are at high risk for bed sores.

In one embodiment, a wide variety of injuries of the CNS may be treated by the methods of the present invention. CNS injury may refer, in one embodiment, to a breakdown of the membrane of a nerve cell, or, in another embodiment, to the inability of the nerve to produce and propagate nerve impulses, or in another embodiment, to the death of the cell. An injury includes damage that directly or indirectly affects the normal functioning of the CNS. The injury may be a structural, physical, or mechanical impairment and may be caused by physical impact, as in the case of a crushing, compression, or stretching of nerve fibers. Alternatively, the cell membrane may be destroyed by or degraded by an illness, a chemical imbalance, or a physiological malfunction such as anoxia (e.g., stroke), aneurysm, or reperfusion. A CNS injury includes, for example and without limitation, damage to retinal ganglion cells, a traumatic brain injury, a stroke-related injury, a cerebral aneurism-related injury, a spinal cord injury, including monoplegia, diplegia, paraplegia, hemiplegia and quadriplegia, a neuroproliferative disorder, or neuropathic pain syndrome.

With injury to the spinal cord of a mammal, connections between nerves in the spinal cord are broken. Such injuries block the flow of nerve impulses for the nerve tracts affected by the injury, with a resulting impairment to both sensory and motor function. Injuries to the spinal cord may arise from compression or other contusion of the spinal cord, or a crushing or severing of the spinal cord. A severing of the spinal cord, also referred to herein as a “transection,” may be a complete severing or, may be an incomplete severing of the spinal cord.

In some embodiments, the methods of treating a subject suffering from a CNS injury or, in other embodiments, spinal cord injury, may be accompanied by treatment of the subject with electrical stimulation of the injured site and the administration of a purine nucleoside, or analog thereof, for example as described in United States Patent Application Publication Number 20040214790A1.

In one embodiment, the dermatological disorder is a wound or a burn. In some embodiments, wounds and/or ulcers are found protruding from the skin or on a mucosal surface or as a result of an infarction in an organ. A wound may be a result of a soft tissue defect or a lesion or of an underlying condition. In one embodiment, the term “wound” denotes a bodily injury with disruption of the normal integrity of tissue structures. The term is also intended to encompass the terms “sore”, “lesion”, “necrosis” and “ulcer”. In one embodiment, the term “sore” refers to any lesion of the skin or mucous membranes and the term “ulcer” refers to a local defect, or excavation, of the surface of an organ or tissue, which is produced by the sloughing of necrotic tissue. Lesion generally relates to any tissue defect. Necrosis is related to dead tissue resulting from infection, injury, inflammation or infarctions. All of these are encompassed by the term “wound”, which denotes any wound at any particular stage in the healing process including the stage before any healing has initiated or even before a specific wound like a surgical incision is made (prophylactic treatment).

Examples of wounds which can be prevented and/or treated in accordance with the present invention are, e.g., aseptic wounds, contused wounds, incised wounds, lacerated wounds, non-penetrating wounds (i.e. wounds in which there is no disruption of the skin but there is injury to underlying structures), open wounds, penetrating wounds, perforating wounds, puncture wounds, septic wounds, subcutaneous wounds, etc. Examples of sores are bed sores, canker sores, chrome sores, cold sores, pressure sores etc. Examples of ulcers are, e.g., peptic ulcer, duodenal ulcer, gastric ulcer, gouty ulcer, diabetic ulcer, hypertensive ischemic ulcer, stasis ulcer, ulcus cruris (venous ulcer), sublingual ulcer, submucous ulcer, symptomatic ulcer, trophic ulcer, tropical ulcer, veneral ulcer, e.g. caused by gonorrhoea (including urethritis, endocervicitis and proctitis). Conditions related to wounds or sores which may be successfully treated according to the invention are burns, anthrax, tetanus, gas gangrene, scalatina, erysipelas, sycosis barbae, folliculitis, impetigo contagiosa, or impetigo bullosa, etc. There is often a certain overlap between the use of the terms “wound” and “ulcer” and “wound” and “sore” and, furthermore, the terms are often used at random. Therefore as mentioned above, in the present context the term “wounds” encompasses the term “ulcer”, “lesion”, “sore” and “infarction”, and the terms are indiscriminately used unless otherwise indicated.

The kinds of wounds to be treated according to the invention include also: i) general wounds such as, e.g., surgical, traumatic, infectious, ischemic, thermal, chemical and bullous wounds; ii) wounds specific for the oral cavity such as, e.g., post-extraction wounds, endodontic wounds especially in connection with treatment of cysts and abscesses, ulcers and lesions of bacterial, viral or autoimmunological origin, mechanical, chemical, thermal, infectious and lichenoid wounds; herpes ulcers, stomatitis aphthosa, acute necrotising ulcerative gingivitis and burning mouth syndrome are specific examples; and iii) wounds on the skin such as, e.g., neoplasm, burns (e.g. chemical, thermal), lesions (bacterial, viral, autoimmunological), bites and surgical incisions. Another way of classifying wounds is as: i) small tissue loss due to surgical incisions, minor abrasions and minor bites, or as ii) significant tissue loss. The latter group includes ischemic ulcers, pressure sores, fistulae, lacerations, severe bites, thermal burns and donor site wounds (in soft and hard tissues) and infarctions.

In other aspects of the invention, the wound to be prevented and/or treated is selected from the group consisting of aseptic wounds, infarctions, contused wounds, incised wounds, lacerated wounds, non-penetrating wounds, open wounds, penetrating wounds, perforating wounds, puncture wounds, septic wounds and subcutaneous wounds.

Other wounds which are of importance in connection with the present invention are wounds like ischemic ulcers, pressure sores, fistulae, severe bites, thermal burns and donor site wounds.

In one embodiment, the use of the SARM compounds as described herein and/or compositions are useful in wound healing as an adjunct to physical therapy/rehabilitation, as an anabolic agent.

In another embodiment, the compositions as described herein are useful in preventing or reversing protein catabolism due to trauma. In another embodiment, the compositions as described herein are useful as: a) adjunct to cauterization therapy (laser or radio) as is used in surgery to promote wound healing, b) adjunct to cryotherapy to promote wound healing, or c) adjunct to chemotherapy to prevent side effects such as alopecia, hypogonadism, muscle wasting, osteopenia, osteoporosis, sarcopenia, increased LDL, TG or total cholesterol, decreased HDL. In another embodiment, the compositions as described herein are useful in chronic catabolic states (coma, wasting conditions, starvation, eating disorders), concomitant bone fracture and muscle damage, critical illness in which muscle or bone wasting are apparent, and/or connective tissue diseases and disorders.

Ischemic ulcers and pressure sores are wounds, which normally only heal very slowly and especially in such cases an improved and more rapid healing is of course of great importance for the patient. Furthermore, the costs involved in the treatment of patients suffering from such wounds are markedly reduced when the healing is improved and takes place more rapidly.

Donor site wounds are wounds which e.g. occur in connection with removal of hard tissue from one part of the body to another part of the body e.g. in connection with transplantation. The wounds resulting from such operations are very painful and an improved healing is therefore most valuable.

The term “skin” is used in a very broad sense embracing the epidermal layer of the skin and in those cases where the skin surface is more or less injured also the dermal layer of the skin. Apart from the stratum corneum, the epidermal layer of the skin is the outer (epithelial) layer and the deeper connective tissue layer of the skin is called the dermis.

In some embodiments, the present invention provides a method for promoting healing of anterior cruciate ligament (ACL) or medial cruciate ligament (MCL) injuries, or accelerating recovery after ACL or MCL surgery.

Example 2 demonstrates that a compound of formula S-(III) is anabolic yet minimally androgenic, thus such compounds may be useful in treating patient groups in which androgens were contraindicated in the past. Compound of formula S-(III) was shown to stimulate muscle growth, whether in the presence or absence of testosterone while exerting anti-proliferative effects on the prostate, thus, in one embodiment, the methods of this invention provide for restoring lost muscle mass in patients with sarcopenia or cachexia.

In one embodiment, the SARM compounds as herein described alter the levels of leptin in a subject. In another embodiment, the SARM compounds as herein described decrease the levels of leptin. In another embodiment, the SARM compounds as herein described increase the levels of leptin in a subject. Leptin is known to have an effect on appetite on weight loss in obese mice, and thus has been implicated in obesity.

The SARM compounds as herein described, in one embodiment, affect circulating, or in another embodiment, tissue levels of leptin. In one embodiment, the term ‘level/s of leptin’ refers to the serum level of leptin. As contemplated herein, the SARM compounds of the present invention have an effect on leptin in vitro and in vivo. Leptin levels can be measured by methods known to one skilled in the art, for example by commercially available ELISA kits. In addition, leptin levels may be determined in in vitro assays, or in in vivo assays, by any method known to a person skilled in the art.

Since leptin is implicated in controlling appetite, weight loss, food intake, and energy expenditure, modulating and/or controlling the levels of leptin is a useful therapeutic approach in treating, preventing, inhibiting or reducing the incidence of obesity in subjects suffering from obesity. Modulating the level of leptin can result in a loss of appetite, a reduction of food intake, and an increase in energy expenditure in the subject, and thus may contribute to the control and treatment of obesity.

The term “obesity” is defined, in one embodiment, as an increase in body weight beyond the limitation of skeletal and physical requirement, as the result of excessive accumulation of fat in the body.

The term “obesity-associated metabolic disorder” refers, in one embodiment, to a disorder which results from, is a consequence of, is exacerbated by or is secondary to obesity. Non-limiting examples of such a disorder are osteoarthritis, type II diabetes mellitus, increased blood pressure, stroke, and heart disease.

Cholesterol, triacylglycerol and other lipids are transported in body fluids by lipoproteins which may be classified according to their density, for example, the very low density lipoproteins (VLDL), intermediate density lipoproteins (IDL), low density lipoproteins (LDL) and high density lipoproteins (HDL).

It has been shown that high levels of LDL-cholesterol in the blood correlate with atherosclerosis which is a progressive disease characterized in part by sedimentation of lipids in inner walls of arteries, particularly of coronary arteries. It has also been shown that a high blood level of LDL-cholesterol correlates with coronary heart disease. Also, a negative correlation exists between blood levels of HDL cholesterol and coronary heart disease.

The level of total cholesterol in blood, which is the sum of HDL-cholesterol, LDL-cholesterol, VLDL-cholesterol and chylomicron-cholesterol, is not necessarily predictive of the risk of coronary heart disease and atherosclerosis.

The correlation between atherosclerosis and LDL cholesterol levels, however, is much higher than a similar correlation between atherosclerosis and total serum cholesterol levels.

In some embodiments, the SARMs as herein described and/or compositions comprising the same may be used for applications in, or treating diseases or conditions associated with a subject having diabetes. In one embodiment, the subject for whom treatment is sought via the methods of this invention is one with diabetic I. Type I diabetes is characterized by autoimmune destruction of pancreatic beta-cells. Markers of immune destruction of the beta-cell are present at the time of diagnosis in 90% of individuals and include antibodies to the islet cell (ICAs), to glutamic acid decarboxylase (GAD), and to insulin (IAAs). While this form of diabetes usually occurs in children and adolescents, it can occur at any age. Younger individuals typically have a rapid rate of beta-cell destruction and present with ketoacidosis, while adults often maintain sufficient insulin secretion to prevent ketoacidosis for many years. Eventually, all type I diabetic patients require insulin therapy to maintain normglycemia.

In one embodiment, this invention provides a method of treating diabetes type II. Type II diabetes is characterized by insulin resistance and at some stage in pathogenesis of the disease, a relative deficiency of insulin secretion. In absolute terms, the plasma insulin concentration (both fasting and meal-stimulated) usually is increased, although “relative” to the severity of insulin resistance, the plasma insulin concentration is insufficient to maintain normal glucose homeostasis. With time, however, there is progressive beta cell failure and absolute insulin deficiency ensues. Most individuals with type II diabetes exhibit intra abdominal (visceral) obesity, fatty liver, which is closely related to the presence of insulin resistance. The patient's liver becomes insulin resistant and glycogen breakdown is uncontrolled and the result is increased and unphysiological glucose delivery to the bloodstream. The liver generatation of cholesterol and VLDL particles is also uncontrolled. In addition, hypertension, dyslipidemia (high triglyceride and low HDL-cholesterol levels; postprandial hyperlipemia), and elevated PAI-1 levels often are present in these individuals. This clustering of abnormalities is referred to as the “insulin resistance syndrome”, or the “metabolic syndrome” or obesity related disorders. Because of these abnormalities, patients with type II diabetes are at increased risk of developing macrovascular complications such as myocardial infarction and stroke.

In one embodiment, this invention provides a method of treating diabetic nephropathy. Diabetic nephropathy is a complication of diabetes that evolves early, typically before clinical diagnosis of diabetes is made. The earliest clinical evidence of nephropathy is the appearance of low but abnormal levels (>30 mg/day or 20 μg/min) of albumin in the urine (microalbuminuria), followed by albuminuria (>300 mg/24 h or 200 μg/min) that develops over a period of 10-15 years. In patients with type 1 diabetes, diabetic hypertension typically becomes manifest early on, by the time that patients develop microalbuminuria. Once overt nephropathy occurs, the glomerular filtration rate (GFR) falls over a course of times, which may be several years, resulting in end stage renal disease (ESRD) in diabetic individuals.

In one embodiment, this invention provides a method of treating diabetic neuropathy. Diabetic neuropathy is a family of nerve disorders caused by diabetes. Diabetic neuropathies cause numbness and sometimes pain and weakness in the hands, arms, feet, and legs. Neurologic problems in diabetes may occur in every organ system, including the digestive tract, heart, and genitalia. Diabetic neuropathies are classified as peripheral, autonomic, proximal, and focal. Peripheral neuropathy causes pain or loss of feeling in the toes, feet, legs, hands, and arms. Autonomic neuropathy causes changes in digestion, bowel and bladder function, sexual response, and perspiration and can also affect the nerves that serve the heart and control blood pressure. Proximal neuropathy causes pain in the thighs, hips, or buttocks and leads to weakness in the legs. Focal neuropathy results in the sudden weakness of one nerve, or a group of nerves, causing muscle weakness or pain. Any nerve in the body may be affected.

In one embodiment, this invention provides a method of treating diabetic retinopathy. The effect of diabetes on the eye is called diabetic retinopathy. Patients with diabetes are more likely to develop eye problems such as cataracts and glaucoma. The affect of diabetic retinopathy on vision varies widely, depending on the stage of the disease. Some common symptoms of diabetic retinopathy are blurred vision (this is often linked to blood sugar levels), floaters and flashes and sudden loss of vision.

In one embodiment, the subject for whom treatment is sought via the methods of this invention is one with glucose intolerance. Glucose intolerance is a pre-diabetic state in which the blood glucose is higher than normal but not high enough to warrant the diagnosis of diabetes.

In one embodiment, the subject for whom treatment is sought via the methods of this invention is one with hyperinsulinemia. Hyperinsulinemia is a sign of an underlying problem that is causing the pancreas to secrete excessive amounts of insulin. The most common cause of hyperinsulinemia is insulin resistance, a condition in which your body is resistant to the effects of insulin and the pancreas tries to compensate by making more insulin. hyperinsulinemia is associated with type II diabetes

In one embodiment, the subject for whom treatment is sought via the methods of this invention is one with insulin resistance. Insulin resistance is a condition in which normal amounts of insulin are inadequate to produce a normal insulin response from fat, muscle and liver cells. Insulin resistance in fat cells results in hydrolysis of stored triglycerides, which elevates free fatty acids in the blood plasma. Insulin resistance in muscle reduces glucose uptake whereas insulin resistance in liver reduces glucose storage, with both effects serving to elevate blood glucose. High plasma levels of insulin and glucose due to insulin resistance often leads to the metabolic syndrome and type II diabetes.

In one embodiment, this invention provides methods of treating, suppressing, inhibiting, reducing the severity, reducing the incidence, reducing the pathogenesis, or delaying onset of, inter alia: (a) diabetes; (b) glucose intolerance; (c) hyperinsulinemia; (d) insulin resistance; (e) diabetic nephropathy; (f) diabetic neuropathy; (g) fatty liver conditions; (h) cardiovascular disease; or (i) cachexia; via the administration of any SARM as herein described and optionally other therapeutic agents, or compositions comprising the same.

Diabetes and the liver obesity is typically associated with elevated levels of free fatty acid (FFAs) that promote lipid accumulation and insulin resistance in target tissues, i.e. reduced action of insulin primarily in skeletal muscle and liver. A prominent role of insulin is to reduce glucose output from the liver. FFAs stimulate hepatic gluconeogenesis which per se does not lead to increased hepatic glucose output as long as it is paralleled by a decrease in hepatic glycogenolysis, a compensatory process referred to as “hepatic autoregulation”. FFAs stimulate insulin secretion and insulin blocks glycogenolysis in part by inhibiting secretion of glucagon, an inducer of glycogenolysis. However, long-term elevated levels of FFAs leads to hepatic insulin resistance and thus breakdown of hepatic autoregulation, resulting in increased hepatic glucose production and development of type II diabetes. Fatty liver and hepatic insulin resistance is a major driving force behind hyperglycemia and type II diabetes. In one embodiment, this invention provides methods that inhibit (improve) the fatty liver, resulting in that the insulin resistance in the liver is inhibited (improved) and thereby solving the basic problem in type II diabetes. In one embodiment, this invention provides a method of treating a human subject having diabetes. In another embodiment, the diabetes is a type I diabetes. In another embodiment, the diabetes is type II diabetes. In one embodiment, this invention provides a method of treating a human subject having glucose intolerance.

Synthesis of (S)-N-(4-Cyano-3-(trifluoromethyl)phenyl)-3-(4-cyanophenoxy)-2-hydroxy-2-methylpropanamide

A mixture of bromoamide ((2R)-3-bromo-N-[4-cyano-3-(trifluoromethyl)phenyl]-2-hydroxy-2-methylpropanamide, 50 g, 0.14 mol), anhydrous K₂CO₃ (59.04 g, 0.43 mol), 4-cyanophenol (25.44 g, 0.21 mol) in 500 mL of 2-propanol was heated to reflux for 3 h and then concentrated under reduced pressure to give a solid. The resulting residue was treated with 500 mL of H₂O and then extracted with EtOAc (2×300 mL). The combined EtOAc extracts were washed with 10% NaOH (4×200 mL) and brine. The organic layer was dried over MgSO₄ and then concentrated under reduced pressure to give an oil which was treated with 300 mL of ethanol and an activated carbon. The reaction mixture was heated to reflux for 1 h and then the hot mixture was filtered through Celite®. The filtrate was concentrated under reduced pressure to give an oil. This oil was purified by column chromatography using CH₂Cl₂/EtOAc (80:20) to give an oil which was crystallized from CH₂Cl₂/hexane to give 33.2 g (59.9%) of (S)-N-(4-cyano-3-(trifluoromethyl)phenyl)-3-(4-cyanophenoxy)-2-hydroxy-2-methylpropanamide as a colorless solid (a cotton type).

Example 2 Androgenic & Anabolic Activity of Compound of Formula S-(III) in Intact and Orchidectomized (ORX) Rat Subjects Materials and Methods

Male Sprague-Dawley rats weighing approximately 200 g were purchased from Harlan Bioproducts for Science (Indianapolis, Ind.). The animals were maintained on a 12 h light/dark cycle with food (7012C LM-485 Mouse/Rat Sterilizable Diet, Harlan Teklad, Madison, Wis.) and water available ad libitum. The animal protocol was reviewed and approved. Anabolic and androgenic activity of Compound of Formula S-(III) in intact animals was evaluated and also compared to oxandrolone, and the dose response in acutely orchidectomized (ORX) animals was evaluated as well. Regenerative effects of Compound S-(III) in chronically (9 days) ORX rats were also assessed.

The compound was weighed and dissolved in 10% DMSO (Fischer) diluted with PEG 300 (Acros Organics, NJ) for preparation of the appropriate dosage concentrations. The animals were housed in groups of 2 to 3 animals per cage. Intact and ORX animals were randomly assigned to one of seven groups consisting of 4 to 5 animals per group. Control groups (intact and ORX) were administered vehicle daily. Compound of formula S-(III) was administered via oral gavage at doses of 0.01, 0.03, 0.1, 0.3, 0.75, and 1 mg/day to both intact and ORX groups.

Castrated animals (on day one of the study) were randomly assigned to dose groups (4-5 animals/group) of 0.01, 0.03, 0.1, 0.3, 0.75, and 1 mg/day, for dose-response evaluation. Dosing began nine days post ORX and was administered daily via oral gavage for fourteen days. The animals were sacrificed under anesthesia (ketamine/xyalzine, 87:13 mg/kg) after a 14-day dosing regimen, and body weights were recorded. In addition, ventral prostate, seminal vesicles, and levator ani muscle were removed, individually weighed, normalized to body weight, and expressed as a percentage of intact control. Student's T-test was used to compare individual dose groups to the intact control group. Significance was defined a priori as a P-value <0.05. As a measure of androgenic activity, ventral prostate and seminal vesicle weights were evaluated, whereas levator ani muscle weight was evaluated as a measure of anabolic activity. Blood was collected from the abdominal aorta, centrifuged, and sera were frozen at −80° C. prior to determination of serum hormone levels. Serum lutenizing hormone (LH) and follicle stimulating hormone (FSH) concentrations were determined.

Results

Prostate weights of intact rats following compound of formula S-(III) (Compound III) treatment were 111%±21%, 88%±15%, 77%±17%, 71%±16%, 71%±10%, and 87%±13% of intact controls following doses of 0.01, 0.03, 0.1, 0.3, 0.75, and 1 mg/day, respectively (FIG. 1). Similarly, seminal vesicle weights of intact rats following Compound III treatment were decreased to 94%±9%, 77%±11%, 80%±9%, 73%±12%, 77%±10%, and 88%±14% of intact controls following doses of 0.01, 0.03, 0.1, 0.3, 0.75, and 1 mg/day, respectively (FIG. 1). Significant increases were seen in levator ani muscle weights of sham animals, however, in all dose groups, when compared to intact controls. Levator ani in intact rats following Compound III treatment were 120%±12%, 116%±7%, 128%±7%, 134%±7%, 125%±9%, and 146%±17% of intact controls for the 0.01, 0.03, 0.1, 0.3, 0.75, and 1.0 mg/day doses, respectively (FIG. 1).

Compound III exhibited anabolic muscle/prostate ratio in castrated rats of 7.56, 4.28, 2.21, 2.19, 1.57 and 1.75 following doses of 0.01, 0.03, 0.1, 0.3, 0.75 and 1 mg/day, respectively.

Compound III partially maintained prostate weight following orchidectomy. Prostate weight in vehicle treated-ORX controls decreased to 5%±1% of intact controls. At doses of 0.01, 0.03, 0.1, 0.3, 0.75, and 1.0 mg/day, Compound III maintained prostate weights at 8%±2%, 20%±5%, 51%±19%, 56%±9%, 80%±28%, and 74±12.5% of intact controls, respectively (FIG. 2).

Compound lit partially maintained seminal vesicle weights in ORX animals, as well. While in castrated controls, seminal vesicle weight decreased to 13%±2% of intact controls, Compound III treated animal weights were 12%±4%, 17%±5%, 35%±10%, 61%±15%, 70%±14%, and 80%±6% of intact controls, following doses of 0.01, 0.03, 0.1, 0.3, 0.75, and 1.0 mg/day, respectively (FIG. 2).

In ORX controls the levator ani muscle weight decreased to 55%±7% of intact controls, while Compound lit treated animals fully maintained and increased levator ani muscle weights at doses >0.1 mg/day, with observed muscle weights of 59%±6%, 85%±9%, 112%±10%, 122%±16%, 127±12%, and 130±2% of intact control weights for the 0.01, 0.03, 0.1, 0.3, 0.75, and 1.0 mg/day dose groups, respectively (FIG. 2).

Pharmacology results following 1 mg/day of Compound III exhibited that prostate weight was 87%±13% of intact control and levator ani muscle weight was 146%±17% of intact control. Compound lit at 1 mg/day maintained prostate weight following orchidectomy at 74±12.5% of intact controls and levator ani muscle weight at 130±2% of intact controls. 0.1 mg/day of Compound III restored 112% of levator ani muscle weight, while 51±20% of prostate weight was restored.

Oxandrolone treatment of ORX animals, was less anabolic than Compound III, with levator ani weights being 50% of intact controls, and not dosage dependent when administered at 0.1-1 mg/day (FIG. 3).

E_(max) and ED₅₀ were determined in each tissue by nonlinear regression analysis in WinNonlin® and presented in FIG. 4. ED₅₀ indicates the dose of Compound III resulting in 50% of the maximal response, which is the E_(max). E_(max) values were 83%±25%, 85%±11%, and 131%±2% for prostate, seminal vesicles, and levator ani, respectively. The ED₅₀ in prostate, seminal vesicles, and levator ani was 0.09±0.07, 0.17±0.05, and 0.02±0.01 mg/day, respectively.

Serum Hormone Analysis

Serum LH and FSH concentrations for the animals are presented in Table 1. LH decreased in a dose-dependent manner in both intact and castrated animals, as a function of treatment with the compound. Following doses >0.1 mg/day, LH levels were below the limit of quantitation (0.07 ng/mL). The 0.1 mg/day dose in ORX animals returned LH levels back to those seen in intact controls. Similar effects were observed with FSH. In intact animals, a significant decrease in FSH levels was observed with the 0.75 and 1 mg/day doses. In ORX animals, a dose-dependent decrease in FSH levels was observed. Doses of Compound of formula S-(III) (Compound III) >0.1 mg/day in ORX animals returned FSH levels to those of intact controls.

Androgenic & Anabolic Activity Following Delayed Dosing

After a delay of 9 days following orchidectomy (chronically castrated rats), Compound of formula S-(III) (Compound III) partially restored both prostate and seminal vesicle weight in ORX animals. Prostate weights were restored to 9%±3%, 11%±3%, 23%±5%, 50%±13%, 62%±12%, and 71%±5%, while seminal vesicle weights were restored 7%±1%, 9%±1%, 23%±8%, 49%±5%, 67%±12%, and 67%±11% of intact controls for 0.01, 0.03, 0.1, 0.3, 0.75, and 1.0 mg/day dose groups, respectively. Compound III fully restored levator ani muscle weight at doses >0.1 mg/day. Levator ani muscle weights were restored to 56%±7%, 82%±9%, 103%±11%, 113%±11%, 121%±7%, and 120%±7% corresponding to doses of 0.01, 0.03, 0.1, 0.3, 0.75, and 1.0 mg/day, respectively. Results are presented graphically in FIG. 5. E_(max) and ED₅₀ values were determined in each tissue by nonlinear regression analysis in WinNonlin® and presented in FIG. 6. E_(max) values were 75%±8%, 73%±3%, and 126%±4% for prostate, seminal vesicles, and levator ani, respectively. The ED₅₀ in prostate, seminal vesicles, and levator ani was 0.22±0.05, 0.21±0.02, and 0.013±0.01 mg/day, respectively.

Example 3 SARM Reduction of Cholesterol Levels Materials and Methods

One hundred Sprague Dawley rats (50 male and 50 female) were divided into five groups (n=10 per gender per group), representing vehicle only (PEG300:40% Cavasol® [75/25 (v/v)]), and four dose groups of Compound of formula S-(III) (Compound III). Animals were administered Compound III once daily by oral gavage according to their most recent body weight with doses of either 0, 3, 10, 30 or 100 mg/kg. During the study period, rats had access to water and a standard laboratory diet of Harlan Taklad Rodent Chow ad libitum. After 28 consecutive days of dosing, animals were fasted overnight, blood samples were collected and serum was obtained. Serum levels of total cholesterol were determined using an automated laboratory assay method.

Results

The male and female rats in the vehicle only group (0 mg/kg) had serum total cholesterol values of 92±13.5 and 102±13 mg/dL respectively. These values are considered within the normal historical range for the testing laboratory. Daily oral doses of Compound lit at or above 3 mg/kg caused a significant reduction in total cholesterol levels in both male and female rats. At 3 mg/kg, compared to vehicle control animals, an approximate 30% reduction in total cholesterol was noted where males and females had 63±17.4 and 74±14.2 mg/dL respectively. Although a slightly greater effect was noted at the highest dose group (100 mg/kg per day), in general, a dose-response relationship was not observed in the reduction of total cholesterol levels in the Sprague Dawley rat. Results are presented graphically in FIG. 7.

Example 4 SARM Promotion of Lean Mass and Reduction of Fat Mass in Human Clinical Trials

Five groups of 24 human subjects per group (12 males and 12 females) of 60 elderly men (age >60) and 60 postmenopausal women (not hypogonadal, not osteoporotic, no exercise program, no controlled diet) were dosed each in a randomized, double-blind study design. Each subject received 0.1 mg, 0.3 mg, 1 mg, or 3 mg Compound III (or placebo of equal volume) in solution or in experimental capsules for 90 days treatment. Total lean body mass (DEXA=dual energy x-ray absorptiometry), fat mass and performance were analyzed.

Results Total Lean Mass (DEXA) Effects

All subjects (average age=64 years)(n=114) exhibited a dose-dependent increase in Lean Body Mass (LBM) following treatment with 0.1 mg, 0.3 mg, 1 mg and 3 mg of Compound of formula S-(III) (Compound III) (FIG. 8).

Treatment with 3 mg Compound III exhibited LBM increase of about 3.1±3.4% compared to baseline with a p<0.0001 (ANOVA). The 1 mg dose of Compound III exhibited an increase of 1.3±2.7% compared to baseline with a p=0.020 (ANOVA) (Table 2).

Females (average age 63 years)(n=56) exhibited a dose-dependent increase in LBM when administered a 3 mg dose of Compound III, with an increase of 1.7 kg compared to baseline and an increase of 1.4 kg compared to placebo with a p=0.02 (ANOVA). Females administered the 1 mg dose of Compound III exhibited an increase of 0.4 kg compared to baseline and no changes compared to placebo with a p=0.884 (ANOVA).

Males (Average age 66 years) (n=58) exhibited a dose-dependent increase in LBM when administered a 1 mg dose of Compound III, with an increase of 0.7 kg compared to baseline and an increase of 1.2 kg compared to placebo with a p=0.03 (ANOVA). Males administered the 3 mg dose of Compound III exhibited an increase of 1 kg compared to baseline and an increase of 1.4 kg compared to placebo with a p=0.005 (ANOVA).

Fat Mass (DEXA) Effects

All subjects exhibited a dose-dependent decrease in total fat for the 0.3 mg, 1 mg and 3 mg doses of Compound III with p=0.242, 0.085 and 0.049 respectively. All subjects exhibited an increase in fat mass for the 0.1 mg (FIG. 9). At 3 mg, the loss was 0.6 kg compared to placebo and 0.3 kg (0.4%) from baseline with a p=0.049 (Table 3).

TABLE 3 Placebo 0.1 mg 0.3 mg 1 mg 3 mg (gr) (gr) (gr) (gr) (gr) Baseline 20807 ± 8689  23355 ± 6019 21555 ± 6694  22561 ± 5659 20493 ± 6932 Mean ± SD(g) Mean  304.7 ± 1105.2 222.47 ± 958.0  −65.4 ± 1055.0 −255.1 ± 948.0  −321.9 ± 1282.0 absolute change from baseline ± SD(g) p-value 0.793 0.242 0.085 0.049 (compared to placebo) Mean % 1.3 ± 7.1  1.3 ± 5.1 0.2 ± 5.1 −1.3 ± 4.4 −0.4 ± 6.9 change from baseline ± SD

The site of fat loss was different among males and females. Males tended to lose from the trunk/abdomen about 1.4 kg compared to the placebo (and 0.5 kg from baseline) with 3 mg (p=0.237) and 1.7 kg compared to the placebo (and 0.8 kg from baseline) with 1 mg (p=0.810) doses. Females tended to lose from the thigh and legs about 1 kg compared to the placebo (and 0.5 kg from baseline) with 1 mg (p=0.038) and 3 mg (p=0.212) doses (Table 4).

TABLE 4 Placebo 1 mg 3 mg Females (g)  529 ± 1210  −514 ± 941 −50.2 ± 909   0.038 0.212 Males (g) 91.8 ± 1013 −8.26 ± 949 −540 ± 1486 0.810 0.237

Total tissue percent fat, relative to lean muscle mass decreased in a dose-dependent fashion, at the 1 mg dose achieving p=0.02 (ANOVA) and at 3 mg, achieving p=0.006 (ANOVA) for all subjects. The decrease in tissue percent fat in women administering 3 mg was highest, compared to administering 1 mg of Compound III, and compared to men administered the same doses.

Performance Effects

In order to analyze the physical performance (which reflects the gain of quality LBM), a stair climb (time and power) study was conducted. Subjects climbed 12 stairs and data was collected as a function of time (speed) and power.

Speed: A dose-dependent decrease in the time needed to climb 12 stairs was observed with the 3 mg dose of Compound of formula S-(III) (Compound III) showing a 15.5% decrease in time (p=0.006, ANOVA).

Power Exerted: A dose-dependent increase in power was observed. In subjects with the 3 mg dose of Compound III, there was 25.5% more power observed than in the placebo group (p=0.005, ANOVA). An increase of 62 watts is approximately 8 times what is considered clinically significant in a middle-aged to elderly non-athlete.

Thus, Compound III built lean body mass in both men and women and lowered the percent body fat. This lean body mass improvement translated to improved performance and power on a stair climb, which indicates, inter alia, that Compound III improves strength and provides a clinical benefit in the elderly and in persons where a condition such as cancer or chronic kidney disease has caused or may cause muscle wasting.

Bone Mass Effects

Bone Mineral Density (BMD) (DEXA): BMD measurements in treated patients were not different from baseline or from placebo. This was not unexpected since 90 days of dosing and measurement is insufficient time to observe meaningful changes in BMD. Bone resorption and turnover markers: In preclinical in vitro and in vivo models of osteoporosis tested, Compound III demonstrated both anabolic and antiresorptive activity affecting both the osteoblasts and osteoclasts.

Safety

Adverse Events (AEs) and Severe Adverse Events (SAEs)—

Compound III was shown to be safe and well tolerated. There were no trends in AEs and there were no SAEs reported during 90 day study period.

Hepatic Effects

It is well known that natural anabolic steroids and synthetic anabolic steroids induce elevations in liver transaminases, in particular ALT and AST. Compound III, in contrast, appeared to minimally affect ALT and AST levels. Of the 120 patients evaluated, 1 female patient exhibited an isolated ALT elevation with no other clinically meaningful changes including no changes in alkaline phosphatase, GTT, and total bilirubin levels. Of the 114 patients that completed the trial, there were no clinically meaningful changes in ALT, AST, alkaline phosphatase, GGT, or bilirubin levels at 3 months post-initiation.

Lipid Profile Effects

Circulating cholesterol, LDL, VLDL, triglyceride and HDL levels were analyzed: High dose testosterone and other anabolic steroids have the ability to reduce cholesterol and profoundly reduce HDL (60-80%). Compound III reduced total cholesterol, LDL, VLDL, and triglycerides in a dose-dependent manner. A dose-dependent reduction in HDL was seen, as well, however not of the magnitude of other orally administered anabolic agents. LDL/HDL ratios, which are a well established way to identify cardiovascular risk, revealed that Compound III treated subjects and placebo groups were in the low or below cardiovascular risk category at all doses.

Body Weight Effects

All subjects total body weight was measured post-administration of Compound III. A dose-dependent change in total body weight of all subjects given a 0.1 mg, 0.3 mg, 1 mg and 3 mg dose of Compound III was observed. Treatment with 0.3 mg or 3 mg Compound III exhibited an increase of 1 kg compared to placebo (and 0.9 kg, from baseline), with a p=0.196 and 0.178 respectively, (ANOVA) (Table 5).

A dose-dependent change in total body weight of women given a 3 mg dose of Compound III was observed, with an increase of 0.8 kg compared to placebo (and 1.63 kg from baseline; Table 6) with a p=0.279 (ANOVA) and with the 1 mg dose a decrease of 0.9 kg compared to the placebo with a p=0.215 (ANOVA).

A dose-dependent change in total body weight of men with the 3 mg dose of Compound III was observed, with an increase of 0.7 kg compared to placebo with a p=0.277 (ANOVA) and with the 1 mg dose an increase of 1 kg compared to the placebo with a p=0.193 (ANOVA).

Hormonal Effects

Testosterone and other anabolic steroid agents suppress LH secretion by feedback inhibition on the pituitary. Less LH leads to lower endogenously produced testosterone. LH levels (U/L) changed relative to placebo groups, as a function of treatment with Compound III.

Administration of 0.1 mg to women led to a 1.2±1.14 U/L increase (p=0.01) in LH, and to a 0.8±1.14 U/L decrease (p=0.466) in men.

Administration of 0.3 mg to women led to a 1.8±1.09 U/L decrease (p=0.403) in LH, and to a 0.1±1.19 U/L increase (p=0.834) in men.

Administration of 1 mg to women led to a 2.6±1.19 U/L decrease (p=0.780) in LH, and to a 0.7±1.14 U/L decrease (p=0.476) in men.

Administration of 3 mg to women led to a 6.4±1.14 U/L reduction (p=0.039) in LH, and to a 0.5±1.09 U/L decrease (p=0.543) in men (Table 7).

SHBG is a sensitive marker of anabolic activity. Anabolic agents lower SHBG levels. In this study, consistent with its anabolic activity, Compound III exhibited a dose-dependent, profound reduction of SHBG levels. Administration of 0.1 mg, 0.3 mg, 1 mg or 3 mg Compound III resulted in reduction of SHBG levels in men and women (Table 8).

Endogenous free testosterone levels decreased relative to placebo groups post-administration of 0.1 mg, 0.3 mg or 1 mg to women, and had no change relative to placebo post administration of 3 mg Compound III (Table 9).

Free testosterone levels in men increased relative to placebo groups post administration of 0.1 mg, 0.3 or 3 mg of Compound III and had almost no change relative to placebo groups post administration of 1 mg Compound III.

A potential side effect of testosterone and other androgenic anabolic steroids is stimulation of the prostate. Measurement of serum PSA is a sensitive measure of stimulation of the prostate gland. Compound III had no effect on serum PSA levels at any dose tested.

Androgenic steroids stimulate sebaceous glands, which play a role in producing sebum and hair. Compound III did not show any significant changes in hair growth in women. Increased sebum production can lead to acne and oily skin, an unwanted side effect. Sebum production was measured in both men and women. Compound III did not affect sebum production in men or women compared to placebo, had no virilization effect and did not cause acne in men and women.

Compound III: a) built lean body mass in both men and women and lowered the percent body fat, b) improved performance and power on a stair climb, thus improving strength and providing a clinical benefit in the elderly and in people where a condition such as cancer or chronic kidney disease has caused or may cause muscle wasting, c) was minimally androgenic thus diminishing risks of hirsitism and prostate cancer currently associated with non-specific androgenic agents, and d) was well tolerated with no serious adverse events reported.

In addition, there were reductions in total cholesterol, LDL and HDL levels. There were no AEs or detrimental changes in other cardiovascular risk factors as measured in the study (such as blood pressure, insulin sensitivity). The data shows that there is a 20% decline in HDL while LDL, triglycerides and total cholesterol are lowered in the presence of increased muscle and decreased body fat.

A 1.5 kg (3.3 lb) improvement in lean body mass is clinically meaningful and consistent with what is seen with other anabolic agents. As men lose a ½ lb. per year this would represent reversing 7 years of muscle loss in 3 months. The lean body mass improvement translates to an improvement in function and muscle power. The improvement was seen in both men and women at the same dose that improved muscle mass. This indicates that if the SARM compound of formula S-(III) delivers the same lean body mass improvement in the elderly population or those people suffering from conditions which accelerate muscle wasting then it would also provide a functional benefit and improved quality of life.

Example 5 Compound of Formula S-(III)-Mediated Reduction of Glucose and Insulin Levels

Five groups of 24 human subjects per group (12 males and 12 females) of 60 elderly men (age >60) and 60 postmenopausal women (not hypogonadal, not osteoporotic, no exercise program, no controlled diet) were dosed each in a randomized, double-blind study design. Each subject received 0.1 mg, 0.3 mg, 1 mg, and 3 mg Compound of formula S-(III) (Compound III) (or placebo of equal volume) in solution or in experimental capsules for 90 days treatment. Glucose and insulin levels were analyzed.

Results

The subjects exhibited dose-dependent decreases in total circulating insulin levels post-administration of 0.3 mg, 1 mg or 3 mg of Compound III for all subjects (all fasting subjects). Treatment with 3 mg Compound III exhibited decrease in insulin levels of about 17.6±43.5 pmol/L compared to baseline with a p=0.043 (ANOVA). The 1 mg dose of Compound III exhibited decrease of 5.43±16.7 pmol/L compared to baseline with a p=0.143 (ANOVA) (Table 10).

Example 6 Compound of Formula S-(III)-Mediated Reduction of Insulin Resistance (HOMA-IR)

Five groups of 24 human subjects per group (12 males and 12 females) of 60 elderly men (age >60) and 60 postmenopausal women (not hypogonadal, not osteoporotic, no exercise program, no controlled diet) were dosed each in a randomized, double-blind study design. Each subject received 0.1 mg, 0.3 mg, 1 mg, and 3 mg Compound of formula S-(III) (Compound III) (or placebo of equal volume) in solution or in experimental capsules for 90 days treatment. Insulin resistance was analyzed, calculated from the mean fasting glucose and insulin levels.

Results

The subjects (all fasting subjects) exhibited dose-dependent decreases in insulin resistance levels post-administration of 0.3 mg, 1 mg or 3 mg of Compound III for all subjects after 86 days. Treatment with 3 mg Compound III exhibited decrease in insulin resistance levels of about 27% compared to baseline (Table 13).

The levels of fasting plasma glucose (FPG), insulin and homoeostasis insulin resistance (HOMA-IR) following administration of Avandia®, glipizide and Compound III exhibited the highest mean % changes from baseline with Compound III. Compound III exhibited −40% mean change from baseline of HOMA-IR, −30% mean change from baseline of insulin and −17% mean change from baseline of FPG, as presented in FIG. 10.

Example 7 Compound of Formula S-(III) Improves Soleus Strength in Rats Materials and Methods

Female Sprague Dawley rats were divided into three groups, representing sham (vehicle) treated, ovariectomized (OVX), sham treated, and OVX animals receiving 3 mg/day Compound of formula S-(III) (Compound III). Compound III and vehicle were administered once daily by oral gavage. After 42 consecutive days of dosing, animals were sacrificed, the left hind limb soleus muscle was dissected and tested for strength analysis. The ratio between P₀, the peak titanic tension (N), and CSA, the cross sectional area (cm²), was determined.

Results

Female rats exhibited improvement in soleus strength. Sham treated and ovariectomized (OVX) sham treated animals exhibited a strength of about 30 N/cm², while OVX-Compound III treated animals exhibited a strength of about 40 N/cm². Results are presented graphically in FIG. 11.

Example 8 SARM Bone Effects Alone and in Combination with the Anti-Resorptive Agent, Alendronate Materials and Methods

Sixty female, virgin, intact Sprague-Dawley rats were obtained from Charles River Laboratories (Wilmington, Mass.) and aged to 23 wks. The animals were housed 2-3 per cage and acclimated to a 12-h light/dark cycle. Food (7012C LM-485 Mouse/Rat Sterilizable Diet, Harlan Teklad, Madison, Wis.) and water were provided ad libitum. The Institutional Animal Care and Use Committee of the University of Tennessee reviewed and approved the animal protocol for this study.

Sham surgeries or ovariectomies were performed on Day 0. The study was comprised of eight treatment groups as follows: (1) intact+vehicle, (2) intact+Compound III, (3) OVX+vehicle (4) OVX+Compound III, (5) OVX+DHT, (6) OVX+E2, (7) OVX+alendronate, (8) OVX+alendronate+Compound III. Doses were administered daily via oral gavage in a vehicle of DMSO:PEG300 (10:90) beginning on Day 1. Animals were sacrificed on Day 45 of the study. Femurs were removed, cleared of soft tissue, and stored in saline soaked gauze at −20° C. until analysis. Nine animals died during the course of the study. These deaths were attributed to surgical complications arising from the ovariectomies and technical errors during oral dosing (i.e., dosing solution delivered into the lungs). Dose groups are listed in the Table 14:

TABLE 14 Gonadal Group Status Treatment Dose Animals/group 1 Intact Vehicle N/A 9 2 Intact COMPOUND III 3 mg/day 9 3 OVX Vehicle N/A 7 4 OVX COMPOUND III 3 mg/day 8 5 OVX Alendronate 1 mg/day 10 6 OVX Alendronate/ 1 and 3 mg/day 8 COMPOUND III

The left femurs were sent to SkeleTech Inc. (Bothell, Wash.) for biomechanical strength (three point bending) and pQCT analysis. A Stratec XCT RM and associated software (Stratec Medizintechnik GmbH, Pforzheim, Germany. Software version 5.40 C) were used for the pQCT analysis. The femur was analyzed at both the mid-shaft and distal regions. The mid-shaft analysis was performed on the region at 50% of the length of the femur. The distal analysis was performed on the region at 20% of the length of the femur starting at the distal end. One 0.5 mm slice perpendicular to the long axis of the femur was used for analysis. Total bone mineral content, total bone area, total bone mineral density, cortical bone mineral content, cortical bone area, cortical bone mineral density, cortical thickness, periosteal perimeter (circumference) and endosteal perimeter were determined at the mid-shaft of the femur. At the distal femur, total bone mineral content, total bone area, total bone mineral density, trabecular bone mineral content, trabecular bone area and trabecular bone mineral density were determined. Following pQCT analysis, the femoral strength was determined by a three-point bending test. The anterior to posterior diameter (APD) (unit: mm) at the midpoint of the femoral shaft was measured with an electronic caliper. The femur was placed on the lower supports of a three-point bending fixture with the anterior side of the femur facing downward in an Instron Mechanical Testing Machine (Instron 4465 retrofitted to 5500)(Canton, Mass.). The length (L) between the lower supports was set to 14 mm. The upper loading device was aligned to the center of the femoral shaft. The load was applied at a constant displacement rate of 6 mm/min until the femur broke. The mechanical testing machine directly measured the maximum load (F_(u)) (unit: N), stiffness (S) (units: N/mm), and energy absorbed (W) (unit: mJ). The axial area moment of inertia (I) (unit: mm⁴) was calculated by the software during the pQCT analysis of the femoral mid-shaft. Stress (σ) (units: N/mm²), elastic modulus (E) (unit: Mpa), and toughness (T) (units: mJ/m³) were calculated by the following formulas: stress: σ=(F_(u)*L*(a/2))/(4*I); elastic modulus: E=S*L³/(48*I); and toughness: T=3*W*(APD/2)²/(L*I).

Statistical analysis was performed by Student's T-test. P-values of less than 0.05 were considered as statistically significant differences.

Male rats were subjected to orchiectomy (ORX), and on days 1-119 were administered perorally by gavage a vehicle, different doses of Compound III (0.1, 1, and 3 mg/d), with or without alendronate (1 mg/d), and alendronate alone. After sacrifice at the indicated times, mice were sacrificed, femurs removed and subjected to pQCT analysis and a 3-point bending assay. Vertebra were harvested as well, and crush assay of L5 was conducted. Tibias were subjected to static and dynamic histomorphometry (calcein).

Results

Trabecular bone mineral density was analyzed by pQCT at the distal femur. Results are shown in FIG. 12A. Significant trabecular bone loss was observed following OVX. Trabecular bone density decreased from 379 to 215 mg/mm³ in the intact and OVX vehicle control groups, respectively. In intact animals treated with Compound III, a slight increase in trabecular bone density to 398 mg/mm³ was observed. In OVX animals treated with Compound III, a significant increase was observed over the OVX vehicle control group to 406 mg/mm³. DHT increased trabecular bone density over the OVX vehicle control group to 360 mg/mm³ and estradiol (E2) increased trabecular bone density to 415 mg/mm³. Alendronate increased trabecular bone density to 480 mg/mm³. The combination therapy of alendronate and Compound III showed additive effects increasing trabecular bone density to 552 mg/mm³.

Rat distal femur representative reconstructions were prepared by standard methodology. As seen in FIG. 12B, while OVX animals show pronounced loss of normal architecture (panel B), OVX Compound III-treated animals provided a structure comparable to intact controls (panel D).

Ovariectomized animals may serve as a model for females suffering from ADIF, and as such, one embodiment of this invention is treatment thereof, for example, via administration of Compound III as exemplified herein.

As evident from FIGS. 12C (BV/TV) and 12D (trabecular number), Compound III prevented gonadectomy-induced losses in trabecular bone in males, as well.

Example 9 Pharmacokinetics of Compound of Formula S-(III)

In order to determine the pharmacokinetics of Compound of formula S-(III) (Compound III), the compound was administered to beagle dogs perorally, and circulating plasma levels, C_(max), t_(max), t_(1/2), AUC and F % (FIG. 13 and the Table 15 below, respectively) were determined. Compound III was rapidly and completely absorbed.

Example 10 Mapping of AR Binding Sites Materials and Methods Reagents

AR and SHC-1 antibodies were obtained from Upstate Biotechnology (Lake Placid, N.Y.), SRC-1 antibody was obtained from Santacruz Biotechnology (Santa Cruz, Calif.). Protein A Sepharose was obtained from Amersham Pharmacia (Piscataway, N.J.). WTS reagent was purchased from Roche (Nutley, N.J.). All cell culture medium was obtained from Invitrogen (Carlsbad, Calif.) and the serum for cell culture obtained from Atlanta Biologicals (Atlanta, Ga.). All other reagents used were analytical grade.

Cell Culture

LNCaP, prostate cancer cells, were obtained from ATCC (Manassas, Va.). The cells were grown in RPMI 1640 (containing 2 mM L-glutamine, 10 mM HEPES, 1 mM sodium pyruvate, penicillin and streptomycin) supplemented with 10% fetal bovine serum (FBS). For the ChIP assays, cells were plated in 150 mm dishes at 10 million cells per dish in RPMI 1640 supplemented with 1% charcoal stripped FBS. The cells were maintained in 1% csFBS for 6 days to reduce basal occupancy of promoters with medium changed on days 1 and 3 and before treatment on day 6.

Chromatin Immunoprecipitation Assay (ChIP)

ChIP assays were performed as described earlier (Narayanan, R. et al., 2005). The proteins were cross-linked by incubation with 1% formaldehyde (final concentration) at 37° C. for 10 min. The cells were washed with 1×PBS twice, scraped in 1 ml of PBS containing protease inhibitors ([1 mg each of aprotinin, leupeptin, antipain, benzamidine HCl, and pepstatin/ml], 0.2 mM phenylmethylsulfonyl fluoride, and 1 mM sodium vanadate), pelleted, and resuspended in SDS lysis buffer (1% SDS, 10 mM EDTA, 50 mM Tris-HCl [pH 8.1]). After lysis on ice for 10 mM, the cell extract was sonicated (Branson sonifier 250) in a cold room eight times for 10 s each at constant duty cycle, with an output of 3 and with incubation on ice after every sonication. The debris was pelleted at 13,000 rpm for 10 min at 4° C., and the supernatant was diluted 10-fold with ChIP dilution buffer (0.01% SDS, 1.1% Triton X-100, 1.2 mM EDTA, 16.7 mM Tris HCl [pH 8.1], 167 mM NaCl). The proteins were precleared with 50 μl of 1:1 protein A-Sepharose beads in TE, 300 μl was reserved as input, and the remaining was incubated with 5 μg of AR or SRC-1 antibody or IgG (negative control) and 2 μg of sheared salmon sperm DNA (Stratagene, La Jolla, Calif.) rotating overnight at 4° C. The protein-DNA-antibody complex was precipitated by incubating with 100 μl of 1:1 protein A-Sepharose beads and 2 μg of salmon sperm DNA at 4° C. for 2 h. The beads were pelleted and washed three times with low-salt wash buffer (0.1% sodium dodecyl sulfate [SDS], 1% Triton X-100, 2 mM EDTA, 20 mM Tris HCl [pH 8.1], 0.15 M NaCl), and twice with 1×TE (10 mM Tris HCl, 1 mM EDTA; pH 8.0). The DNA-protein complex was obtained by extracting the beads with 50 μl of freshly prepared extraction buffer (1% SDS, 0.1 M NaHCO₃) three times. The cross-linking of the DNA protein complex was reversed by incubating at 65° C. for 6 h. The DNA was extracted with a QIAquick PCR purification kit (QIAGEN, Valencia, Calif.) in 25 μl final volume of TE.

Real-Time PCR

The realtime PCR was performed on an ABI 7300 (Applied Biosystems) using TaqMan PCR master mix at universal condition. The numbers on the y axis of the ChIP assay results were obtained by dividing the arbitrary quantitative PCR numbers obtained for each sample by the respective input. All promoter array results were validated using primers and taqman probes (Biocource, CO) given in the following Table 16.

Promoter Array

H20K promoter array from AVIVA systems biology (San Diego, Calif.) was used for these experiments. The array consists of 20,000 probe pairs mapped to about 19,600 unique proximal promoter regions. Proximal promoter regions between −1.0 KB to +300 bp were spotted on this array. Before hybridization, the efficiency of the ChIP assay was tested on PSA enhancer using quantitative PCR. Manufacturer's protocol was followed for the hybridization using Cy5 label for the immunoprecipitated samples and Cy3 label for total input DNA. The hybridized slides were scanned using a Gene Pix 4 scanner. Resulting background subtracted median intensities for both the Cy3 and the Cy5 channels were used to calculate normalized log₂ (Cy5/Cy3) or M values in the limmaGUI⁴² package developed for the R statistical language. In limmaGUI, background subtraction was set to minimum replacing confounding negative or zero intensities with very small positive numbers. Default settings were used for spot quality weighting and all arrays were within-array normalized using the global-loess function and between-array normalized using the aquantile method as needed. A one-tailed students t-test was used to determine significance (P<0.05) of treatment hybridization versus vehicle control where the mean of replicate normalized M-values was greater in treatment than in control.

Gene Ontology (GO) Functional Analyses

The software package ErmineJ⁴³ was used to mine statistically overrepresented GO terms from each experimental group and successfully mapped 80% of array targets to their GO annotation. An implementation of the receiver operator characteristic (ROC) method was used in ranking −log(p-values) (NLP) of all genes showing recruitment and performing the wilcoxon rank sum test to examine significance of gene sets (minimum size 20) associated with GO terms containing a greater number of high ranking genes than would be expected if rankings were randomly distributed amongst all gene sets. Only the most significant NLP of replicates within each array were considered. p<0.05 (uncorrected for multiple comparisons) were reported. Gene product: Go term associations used were retrived using SOUCE and the GO database (Ashburner, M. et al. 2000)

Orthlogous Promoter Determination and Retrieval

All human-mouse orthologs were determined using NCBI's Homologene⁴⁴. Using only orthologous Reference Sequences (RefSeq), 5000 base pairs upstream of the transcription start site (TSS) and 2000 base pairs down stream were retrieved using UCSC's Genome Browser (H. Sapiens and M. musculus NCBI Build 35). 50-60% (712 genes) of the genes of interest contained the complete annotation described and were searched.

Animal Experiments

Five male Sprague Dawley rats per group (300 g) from Harlan (Indianapolis, Ind.) were housed with three animals per cage and were allowed free access to tap water and commercial rat chow (Harlan Teklad 22/5 rodent diet—8640). During the course of the study, the animals were maintained on a 12 hr light:dark cycle. This study was reviewed and approved by the Institutional Laboratory Care and Use Committee of The University of Tennessee. The animals were dosed daily for 15 days with 3 mg/day of SARM or DHT or vehicle (Polyethylene Glycol). Dosing solutions were prepared daily by dissolving drug in dimethyl sulfoxide (DMSO) and diluting in polyethylene glycol 300 (PEG 300). At the end of 15 days, the animals were sacrificed and the weights of prostate and levator ani measured.

Bone Marrow Culture

Cell culture materials were obtained from Invitrogen (Carlsbad, Calif.). The femurs were first rinsed in 70% ethanol and were then washed three times with 5 ml each of penicillin and streptomycin. Both ends of the femurs were snapped and the bone marrow cells were flushed with 15 ml of MEM with penicillin, streptomycin and fungizone into a 50 ml conical tube and stored on ice. The bone marrow cells were pooled and were centrifuged at 1000 rpm for 5 min in a clinical centrifuge. The cells were resuspended in phenol red-free MEM supplemented with 10% charcoal-stripped serum, penicillin, streptomycin and fungizone. The cells were triturated through a 22 g needle, counted under microscope, and were plated at 1.5 million cells per well of a 6 well plate in phenol red-free MEM supplemented with 15% charcoal-stripped serum, penicillin, streptomycin, 300 ng/ml fungizone, 0.28 mM ascorbic acid, and 10 mM (3-glycerophosphate to differentiate towards the fibroblast/osteoblast lineage. In separate wells, 2.5 million cells per well were plated in 24 well plates in phenol red-free MEM supplemented with 10% charcoal stripped serum, penicillin, streptomycin, and 300 ng/ml fungizone to differentiate towards the osteoclast lineage. The medium was changed on day 2 and the cells were treated with the compound of interest. Osteoclast cultures were performed in the presence of RANK Ligand (50 ng) and GM-CSF (10 ng) to induce osteoclastogenesis. Medium was completely changed every third day for osteoclast cultures. For fibroblast cultures, half the culture medium was changed every third day to leave the growth factors secreted by the cells.

Staining of Cells

At the end of 12 days, the cells were fixed in 10% buffered formalin for fibroblast cultures and in 4% formaldehyde in PBS for osteoclast cultures. The fibroblasts were stained for alkaline phosphatase activity and the O.D. at 405 nm was measured using a spectrophotometer as described earlier. The osteoclasts were stained for Tartarate Resistant Acid Phosphatase Activity (TRAP) and cells having 2 or more nuclei were counted under the microscope.

RNA Analysis and Reverse Transcriptase Polymerase Chain Reaction

LNCaP cells were plated at 700,000 cells per well of a 6 well plate in RPMI supplemented with 1% csFBS or in full serum. The cells were maintained for 3 days and were treated with vehicle, DHT or SARM. RNA was isolated using Trizol (Invitrogen) and the expression of various genes measured using TaqMan primer probe mix from Applied Biosystems using one step rtPCR master mix on an ABI 7300 realtime PCR machine. The expression of individual gene is normalized to 18S rRNA levels.

Growth Assay

LNCaP cells were plated at 10,000 cells per well of a 96 well plate in RPMI supplemented with 1% csFBS. The cells were treated for 72 hrs with the indicated concentrations of DHT or SARM. The cell viability at the end of 72 hrs measured using WTS assay reagent.

Co-Immunoprecipitation

LNCaP cells were plated at 4 million cells per 10 cm dish in RPMI supplemented with 1% csFBS. The cells were maintained in 1% csFBS containing medium for 2 days. The medium was changed and were treated with vehicle, 100 nM DHT or SARM for 1 hr. Protein was extracted in Homogenization buffer (0.05 M potassium phosphate, 10 mM sodium molybdate, 50 mM sodium fluoride, 2 mM EDTA, 2 mM EGTA, and 0.05% monothioglycerol [pH 7.4] containing 0.4 M NaCl and the protease inhibitors mentioned above) by three freeze thaw cycles in dry ice ethanol bath. Equal amounts of protein (100 μg) were immunoprecipitated with SHC-1 antibody or IgG over night rotating at 4° C. The protein antibody complex was precipitated by the addition of protein A sepharose for 2 hrs. The beads were pelleted and washed three times with low salt wash buffer and twice with TE. The proteins were extracted from the beads by boiling for 10 min with 2× Laemmli buffer. The protein extracts were fractionated on a 6.5% SDS-PAGE, transferred to a nitrocellulose and western blotted with SRC-1 antibody.

Results Mapping of AR Binding Sites in Response to DHT and SARM

A chromatin immunoprecipitation assay (ChIP) assay was coupled with DNA microarray to determine the genome wide-binding of AR to various proximal promoter regions. LNCaP cells were treated with DHT or SARM, and equal amounts of DNA were hybridized to the transcription factor promoter array. AR significantly associated with 1303 of the promoter regions for known protein-coding genes in the presence of DHT or SARM (FIG. 14A). AR bound to nearly 6.5% of the promoters spotted on the array. Although DHT and SARM stimulated the recruitment of AR to a similar number of gene promoters, only 118 of the 1303 promoters were shared. In response to DHT, 626 promoters were uniquely occupied, while in response to SARM, 559 promoters were uniquely occupied by AR. Functional analysis of the genes revealed profound differences in the functional activity of these genes (FIG. 14B). DHT promoted recruitment of the AR to 71% and 63% of the genes associated with cell growth and extracellular matrix, respectively, while only 29% and 31%, respectively of these promoters were occupied by the AR in response to SARM. In contrast, SARM stimulated recruitment of the AR to 63% of the genes associated with an external stimulus (eg. intracellular signaling pathways). Genes associated with cytoskeleton, reproduction, development, transcription and metabolism were associated about equally with DHT and SARM treatment. A comparative genomics search was used to identify the presence of AREs in the 1303 gene promoters. Totally 712 of the 1303 gene promoters were sufficiently annotated in the human and mouse database for this search. 78 of 350 searched promoters recruiting AR in response to DHT contained AREs, whereas 69 of 277 SARM-responsive promoters were classified as ARE positive (FIG. 14C).

Mapping of SRC-1 Binding Sites in Response to DHT and SARM

SRC-1 was efficiently recruited in the presence of DHT and SARM (FIG. 15A). Using promoter array and identical conditions to that used for AR, we mapped SRC-1 binding to 285 promoters (FIG. 15B). DHT recruited SRC-1 to 498 promoters, SARM recruited SRC-1 to 640 promoters and DHT or SARM commonly recruited SRC-1 to 147 promoters. Functional analysis of the genes revealed some significant differences in the functional activity of these genes (FIG. 15C). DHT promoted recruitment of SRC-1 to 67% and 28% of the genes associated with reproduction and cytoskeleton, respectively, while 33% and 55%, respectively of the promoters were occupied by SRC-1 in response to SARM. Genes associated with other classes were associated equally with DHT and SARM. A comparative genomics search similar to that performed with AR was performed with the list of promoters occupied by SRC-1 to identify the presence of AREs. FIG. 15D shows that 77 of the 269 searched promoters recruiting SRC-1 in response to DHT contained AREs, whereas 66 of 317 SARM-responsive promoters were classified as ARE positive. Array results were validated by performing realtime PCR on the DNA pool obtained from ChIP experiments in LNCaP cells using SRC-1 antibody.

The tissue selective responses of the compounds of this invention may be a result of their interaction with a particular androgen receptor subtype, as a function of tissue expression, or in some embodiments, as a function of tissue distribution of the particular compound, or tissue distribution of a metabolite thereof, or a function of the interaction of the compound with a 5α-reductase, or by any other mechanism.

In some embodiment, tissue selectivity is a function of the ligand affinity, or in some embodiments, intrinsic activity of the compound, for example, in terms of the ligand-induced receptor conformational change. In some embodiments, the tissue selectivity is a function of the efficacy of the compound in provoking a response in terms of effects on gene expression, regulator recruitment, interactions with components of the transcriptional machinery, or others.

In this context, Compound III has been shown herein to bind the androgen receptor (K_(i)=10.5 nM), as well as the serotonin transporter (K_(i)=2.55 μM).

Validation of Promoter Array

To validate the array results, ChIP assays were performed in LNCaP cells with primers flanking the promoters of representative genes to which the AR was recruited in the presence of DHT (MSX-1), DHT and SARM (APIG1, AXIN1) or SARM (NFkB1E). FIG. 16A shows successful validation of the array results.

Androgen receptor (AR) is known to be involved in both gene activation and repression. As such, the transcriptional status of genes was examined to which AR was recruited. RNA from LNCaP cells treated with vehicle, DHT or SARM were quantified using rtPCR. FIG. 16B shows the transcription of several (SHC-1, MSX-1, AXIN1, NFkB1E and GAS7).

Example 11 Effect of Compound of Formula S-(III) on Muscle Wasting and Physical Function in Patients with Cancer Materials and Methods

Patients

Eligible patients were men aged >45 years and postmenopausal women who were non-obese, defined as a body mass index (BMI) ≦35 kg/m². Additional inclusion criteria included ≧2% weight loss in the 6 months before screening, life expectancy >6 months, and an Eastern Cooperative Oncology Group (ECOG) score of ≦1. Patients must have been diagnosed with non-small cell lung cancer (Stage 2, 3, or 4), colorectal cancer (Stage 2, 3, or 4), non-Hodgkin lymphoma, chronic lymphocytic leukemia, or breast cancer (Stage 3 or 4), and had not yet begun chemotherapy or were between chemotherapy cycles. Key exclusion criteria included a history of active/uncontrolled congestive heart failure, hypertension, chronic hepatitis, hepatic cirrhosis, or infection with human immunodeficiency virus or hepatitis A, B, or C. Patients with aspartate aminotransferase/alanine aminotransferase (ALT) levels >3× the upper limit of normal (ULN) or total bilirubin levels >2 mg/dL were excluded. Patients currently taking testosterone, oxandrolone, or testosterone-like agents (e.g., dehydroepiandrosterone, androstenedione and other androgenic compounds, including herbals) within the past 30 days (or 6 months if long-term depot), megestrol acetate, dronabinol, or any prescription medication intended to increase appetite or treat unintended weight loss were also excluded.

Study Design

A randomized, double-blind, placebo-controlled, multicenter efficacy and safety study of Compound of formula S-(III) (Compound III) in patients with cancer was conducted. Eligible patients were randomized in a 1:1:1 ratio to receive Compound III 1 or 3 mg or matching placebo orally once daily for up to 113 days. Randomization was stratified to balance the treatment groups by cancer diagnosis.

Results

Patient Disposition and Demographics

A total of 159 patients were randomized and received ≧1 dose of study drug (placebo, n=52; Compound III 1 mg, n=53; or Compound III 3 mg, n=54). Among these patients in the intent-to-treat (ITT)/safety population (N=159), 53 discontinued treatment. The most common reason for discontinuation was the occurrence of an AE (n=18; 11.3%). There were no significant between-group differences in the rate of or reasons for discontinuation. The percentage of patients who had an on-study DXA scan and were included in the modified ITT (MITT) population (n=114) was similar between the placebo (73.1%) and Compound III 3-mg (75.9%) groups, but was slightly lower in the Compound III 1-mg group (66.0%).

Baseline demographic and clinical characteristics were generally similar across treatment groups (Table 17). Among patients in the safety population, mean age was 65.9 years and the majority of patients were male (64.8%) and Caucasian (89.9%). At baseline, mean weight loss in the 6 months before screening was substantial (˜9%) in all treatment groups. In both the safety and MITT populations, there were no statistically significant differences from placebo in the percentage of weight loss in the previous 6 months, total LBM, or hand grip strength in Compound III 1- or 3-mg treatment groups (Table 17).

Efficacy

There was a statistically significant increase from baseline to Day 113/EOS in total LBM in patients who received Compound III 1 mg (P<0.001) and Compound III 3 mg (P=0.046), but not in those who received placebo (Table 18). The difference between the Compound III 3-mg group and the placebo group was statistically significant (mean change, P=0.041; percentage change, P=0.023). Patients who received Compound III 1 mg also had an increase in total LBM compared with patients receiving placebo, although this difference was not statistically significant. In addition to the pre-specified local reads of DXA scans, a post hoc analysis of the DXA scans was also conducted by a central radiology group. These results were consistent with those of the primary local read (data not shown).

In the MITT population, an increase (˜1 kg) in scale weight was observed by Day 113/EOS in all treatment groups (1.2%-1.5% change from baseline). Compared with placebo, patients who received Compound III 1 or 3 mg had numerically greater gains in scale weight from baseline to Day 29 (0.59 and 0.88 kg, respectively, vs 0.49 kg) and Day 57 (1.17 and 1.31 kg, respectively, vs 0.5 kg). These data are consistent with the changes seen in total LBM in these treatment groups.

There was a significant increase from baseline to Day 113/EOS in stair climb power among patients who received Compound III 1 or 3 mg (P≦0.002, stairs 1-12), but not those who received placebo (FIG. 17). This increase was significantly different from placebo in the Compound III 1-mg group (P=0.034), but not in the Compound III 3-mg group (P=0.058). A similar trend was observed for each set of stairs, with significant differences between the Compound III 1-mg and placebo groups for stairs 1-4, stairs 4-8, and stairs 8-12 (P≦0.036 for all comparisons). The time required to climb all 12 stairs increased slightly from baseline to Day 113/EOS in patients who received placebo, but was significantly decreased (P≦0.008) in both of the Compound III treatment groups (FIG. 18). These changes were significantly different compared with placebo in the Compound III 1-mg (P=0.007) and Compound III 3-mg (P=0.028) treatment groups.

The percentage changes from baseline to Day 113/EOS in hand grip strength (both hands) increased in both Compound III treatment groups (1 mg, 15.06%; 3 mg, 4.93%). Patients in the placebo group experienced a decrease in hand grip strength (−1.07% from baseline to Day 113/EDS). Compared with placebo, there was a significant difference in the percentage change from baseline in the Compound III 1-mg group (P=0.05).

A post hoc analysis demonstrated a significant and clinically meaningful improvement in QoL parameters in patients that showed a ≧1-second improvement in stair climb time compared with patients who did not show this improvement (P≦0.028). A similar statistically significant improvement in QoL measurements from baseline to Day 113/EOS was seen in patients who had an increase in stair climb power of >9.8 watts compared with patients without this change (P≦0.016).

Compound III is well tolerated and safe in patients with cancer cachexia and resulted in significant increases in LBM and improvements in physical function. Importantly, this study provides evidence of clinically meaningful improvements in QoL among patients who experienced improvements in physical function (as assessed by stair climb power) with Compound III treatment. The use of Compound III at an earlier stage of disease, possibly as a first-line treatment, may allow for a greater clinical benefit.

Example 12 Effect of Compound of Formula S-(III) on Physical Function in Patients with Non Small Cell Lung Cancer (NSCLC)

This randomized, double-blind, placebo-controlled, multicenter phase II trial evaluated the efficacy and safety of Compound III, a selective androgen receptor modulator, in cancer patients with muscle wasting.

Patients and Methods:

Eligible patients were non-obese men aged >45 years or postmenopausal women with cancer (colorectal, NSCLC, non-Hodgkin's lymphoma, chronic lymphocytic leukaemia and breast cancer) and ≧2% weight loss in the previous 6 months. Patients (N=159) received Compound III 1 mg, 3 mg, or placebo orally once daily for up to 113 days. Total LBM was evaluated as the primary endpoint using dual energy x-ray absorptiometry. The primary endpoint was change in lean body mass measured by dual energy x-ray absorptiometry. Secondary endpoints included QoL and physical function with clinical benefit defined as 10% improvement in physical function assessed by stair climb power (responder analysis). LBM, physical function and QoL were further assessed in the subset of NSCLC subjects (N=61).

Results:

Among NSCLC subjects, 28 were included in the physical function analysis (MITT). Total LBM and stair climb power increased in Compound III treated subjects compared to baseline (Table 19). LBM improved by a median of 0.99% from baseline to Day 113/end of study with Compound III (N=21, MITT; P=0.272) and decreased by 0.83% in placebo (N=10, MITT). Stair climb power increased by a median 15.15% (N=18, MITT; P=0.076) in the Compound III treated subjects compared to baseline and increased by 1.14% (N=10, MITT) in the placebo subjects.

Seventy-eight percent of NSCLC patients treated with Compound III responded, as defined by a 10% improvement in stair climb power, compared to 30% treated with placebo (P=0.02). Physical function was positively correlated with QoL as assessed by the Functional Assessment of Anorexia/Cachexia Therapy (FAACT) questionnaire further substantiating clinical benefit (Spearman correlation coefficient=0.60, P=0.001) (FIG. 19).

Example 13 Effect of Compound of Formula S-(III) on Overall Survival in Patients with Cancer Cachexia

Subjects (n=159) were randomized to oral Compound of formula S-(III) (Compound III) (1 or 3 mg) or placebo (pbo) daily for 16 weeks. Subjects were males >45 y and postmenopausal females, had experienced ≧2% weight loss in the 6 months prior to randomization, had a body mass index (BMI) <35 and either NSCLC, colorectal cancer, non-Hodgkin's lymphoma, chronic lymphocytic leukemia or breast cancer.

In placebo (pbo) subjects in the intent to treat (ITT) population, overall survival was significantly (P=0.003, log rank) reduced in subjects with >8% weight loss compared to subjects with ≦8% weight loss. Among NSCLC subjects (n=61) pbo subjects with >8% weight loss demonstrated a similar survival disadvantage (P=0.04); 4 month Kaplan-Meier estimates 100% vs 49%±14.8%. In Compound III treated subjects in both the ITT and NSCLC groups, increased weight loss did not negatively affect survival.

Preceding weight loss among NSCLC patients not treated with Compound III is predictive of decreased overall survival. In this 16 week study, NSCLC subjects randomized to placebo with >8% weight loss at baseline were 2 times more likely to die than subjects with ≦8% weight loss. In the Compound III group weight loss was not predictive of overall survival. These data suggest that Compound III treatment may overcome the negative prognostic effect of >8% weight loss.

Example 15 Combination Treatment of Compound of Formula S-(III) with Platinum and Taxane (Study A) and Combination Treatment of Compound of Formula S-(III) with Platinum and Non-Taxane (Study B)

Methods

A 3 mg dose of Compound III was studied in two Phase 3 clinical trials (Study A and Study B) to prevent and treat muscle wasting in patients with non-small cell lung cancer (NSCLC). In each of these placebo controlled, double blind, add-on clinical trials, approximately 325 patients with stage III or IV NSCLC were randomized to oral daily doses of placebo or Compound III 3 mg at initiation of first-line chemotherapy based upon the chemotherapy regimen prescribed; platinum+taxane (Study A, n=321) or platinum+non-taxane (Study B, n=320). Patients (males and postmenopausal females 30 y with ECOG 1) received either Compound III 3 mg combination therapy or placebo for 5 months. The platinum used was cisplatin or carboplatin. The taxane used was docetaxel or paclitaxel. The non-taxane used was gemcitabine, pemetrexed or vinorelbine.

Lean body mass (LBM) was measured by dual-energy x-ray absorptiometry (DXA) and improvement of physical function was assessed by stair climb power (SCP) at days 84 (primary endpoints) and 147 (secondary endpoints). The stair climb power was measured according to the following equation: Power=9.8 m/s²×stair height [m]×weight [kg]/stair climb time [s].

Secondary endpoints also included an assessment of whether Compound III-treated patients had an improved quality of life and reduced healthcare resource utilization compared to placebo.

Overall survival is being assessed as an additional safety endpoint.

Table 21 provides the baseline characteristics of Study A (combination treatment of Compound III, platinum and taxane vs. a placebo of combination of platinum and taxane) and Study B (combination treatment of Compound III, platinum and non-taxane vs. a placebo of platinum and non-taxane).

Results:

Compound III 3 mg once daily had a significant effect on LBM through Day 84 and 147 in both studies:

Study A: p=0.0003 (day 84) and <0.0001 (day 147), as presented in Table 22B and FIGS. 20A-20B;

Study B: p=0.0227 (day 84) and 0.0036 (day 147), as presented in Table 23B and FIGS. 23A-23B, using continuous variable analyses.

By the responder* analysis, a larger proportion of patients receiving Compound III maintained or increased LBM at Day 84 and 147 in both studies (Study A: p=0.036 (Table 22A) and 0.026 (Table 22C); Study B: p=0.113 (Table 23A) and 0.013 (Table 23C)), as compared to placebo. *Responder in this case defined as a subject that maintained or demonstrated an increase in LBM at Day 84 as compared to baseline and that demonstrated a 10% or greater increase in stair climb power [watts] at Day 84 as compared to baseline.

A non-responder is a subject who does not meet the definition of response or does not have the Day 84 assessment. Variations on the responder analyses are presented in Tables 22C-22F (Study A) and Tables 23C-23F (Study B).

The effect on LBM in Study B was achieved despite declining of body weight (FIGS. 24A-24B).

In a post-hoc analysis, regardless of treatment, patients with a ≧1 kg increase in LBM were more likely to demonstrate at least a 10% increase in SCP compared to patients who did not have a ≧1 kg increase in LBM (Study A: 43.7% vs 29.3%, p=0.0250; and Study B: 40.5% vs 26.5%, p=0.0321) (FIGS. 35 and 36). The percentage improvement in SCP from baseline to day 84 differed significantly between patients with and without a 1 kg increase in LBM: 9.1% vs −1.0% in Study A (p=0.0022) and 7.7% vs −0.0.6% in Study B (p=0.0046).

Importantly, a larger proportion of Compound III treated patients, with 1 kg or greater increases in LBM, demonstrated at least a 10% increase in SCP (Study A: p=0.0698, ≧1 kg 46.4%, <1 kg 29.6%; and Study B: p=0.0335, ≧1 kg 39.6%, <1 kg 20.4%), while this same trend was not observed in placebo treated patients (Study A: p=0.3149, ≧1 kg 38.7%, <1 kg 29.0%; and Study B: p=0.2852, ≧1 kg 41.5%, <1 kg 31.3%) (FIG. 36). This observation suggests that SCP improvements, in both trials, may be related to Compound III dependent increases in LBM.

Post-hoc landmark survival analyses at Day 84 suggest improved survival in patients who maintained or increased LBM in both clinical trials, regardless of treatment. (FIG. 31). Published studies have reported that loss of muscle is associated with shorter survival in cancer patients. Studies A and B support these primarily retrospective analyses with a prospective assessment of the relationship between LBM and overall survival in advanced lung cancer patients (FIGS. 32-34).

NSCLC patients on first line platinum doublet chemotherapy have accelerated muscle loss and physical function decline in a background of progressive weight loss. Compound III maintained or improveed muscle mass while subjects on chemotherapy alone continued to lose muscle mass over a relatively short period of time (3 months). Compound III stopped the physical function decline while subjects on chemotherapy alone continued to decline in physical function. Prevention and treatment of muscle loss was demonstrated in both Study A and Study B clinical trials.

Lean body mass was observed to be an important prognostic indicator for increased survival in both chemotherapy and chemotherapy plus Compound III NSCLC patients. Compound III maintained and built muscle better than chemotherapy alone.

In Study A and Study B, declines in both lean body mass and stair climb power were observed in placebo group.

Statistically and clinically meaningful differences between Compound III (Study A) and placebo were observed for both lean body mass (muscle) and stair climb test (physical function).

Statistically and clinically meaningful differences between Compound III (Study B) and placebo were observed for lean body mass (muscle).

The effect on LBM in Study A and Study B was achieved despite declining body weights (FIGS. 21A-21B and 24A-24B).

Different populations and chemotherapy side effects (anemia & vomiting (See Example 16)) in Study B appear to explain physical function responses. Evidence suggests longer duration of therapy or increasing Compound III dose may overcome these side effects of chemotherapy

Compound III was very well tolerated in both Study A and Study B. In general, patients that maintained or increased LBM had greater increases in SCP and survived longer.

Example 16 Adverse Events of Study A and Study B

Table 24 provides treatment emergent adverse events of subjects treated with the combination of Compound III, platinum and taxane (Study A) and subjects treated with Compound III, platinum and non-taxane (Study B).

Based on the results, adverse events were observed in ≧5% subjects with a difference of ≧2% between placebo and Compound III.

TABLE 25 Differences in selected AEs between the Studies STUDY A STUDY B (Platinum + Taxane) (Platinum + Nontaxane) Adverse Event Placebo Cmpd III Placebo Cmpd III Anemia 27.3% 28.8% 47.9% 50.9% Neutropenia 18.6% 12.5% 33.9% 30.9% Leukopenia 3.1% 3.8% 17.0% 15.8% Thrombocytopenia 5.6% 3.8% 17.6% 18.8% Nausea 32.3% 35.6% 44.2% 44.8% Vomiting 16.1% 18.1% 29.1% 27.3% Constipation 8.6% 10.6% 15.2% 12.7% Asthenia 12.4% 20.6% 16.4% 15.2% Decreased appetite 16.8% 6.9% 17.0% 19.4% Arthralgia 13.7% 16.9% 2.4% 1.8% Alopecia 32.3% 33.8% 10.3% 10.9% Diarrhoea 14.9% 11.3% Dyspnoea 7.5% 13.1% 6.7% 12.7% Peripheral Sensory 5.6% 11.9% Neuropathy Pneumonia 8.7% 5.0% Haemoptysis 8.7% 4.4% 6.7% 3.6% Pain in Extremity 5.6% 8.1% Chest pain 7.3% 3.6% Cough 9.1% 11.5% Hypokalemia 7.3% 3.0% Blood creatinine 9.1% 13.9% increased

The non responders also had adverse effects as demonstrated in FIGS. 26 and 27.

FIG. 26 demonstrates that the plasma concentrations of Compound III were lower in Study B LBM nonresponders. FIG. 27 (left panel) demonstrates that LBM nonresponders who reported nausea and vomiting had lower Compound III levels in Study B. FIG. 27 (right panel) demonstrates that Compound III levels were similar in LBM responders and non-responders who did not report nausea and vomiting.

Only minor differences in adverse events were observed between the groups treated with Compound III 3 mg and placebo in the Study A and Study B, however, there were notable differences in the adverse event profile between studies with anemia and other hematologic toxicities more prevalent in the Study B (platinum plus non-taxane) clinical trial.

Example 17 Hemoglobin Concentrations Following Study A and Study B

FIG. 28 shows that Study B (platinum+nontaxane) subjects had lower hemoglobin levels. However, the hemoglobin levels did not affect LBM response (Table 26 and FIG. 29). Current understanding of the ability of Compound III to build or maintain LBM is not thought to rely on sufficient hemoglobin for muscle oxygenation and respiration.

TABLE 26 Responders analyses: Lean Body Mass (LBM) maintain or increase Hemoglobin (g/dL), median (range) Nonresponders Responders Study A (n = 132) (n = 116) p-value Day 84 11.80 (7.10-20.80) 11.90 (8.5-15.80)  0.2587 Hemoglobin (g/dL), median (range) Nonresponders Responders Study B (n = 90) (n = 134) p-value Day 84 10.50 (7.00-15.50) 10.70 (7.70-14.60) 0.7845

However, hemoglobin levels were related to the ability of LBM responders to have a stair climb test benefit (Table 27 and FIG. 30). Anemia, manifest in this case as a reduction in hemoglobin, is a well-established cause of weakness, fatigue, deconditioning, and loss of physical function which could influence the results of a functional endpoint such as SCP in response to maintained or increased LBM. The overall lower hemoglobin levels in Study B relative to Study A suggest that LBM responders in Study B may have lacked sufficient hemoglobin to translate drug mediated LBM effects into SCP performance

Example 18 Studies of Compound of Formula S-(III) on Knockout Mice

Dystrophin (DMD) homozygous null nice (−/−) and utrophin (UTRN) heterozygous mice (+/−) were obtained from JAX labs. The animals were used to breed DMD (−/−) UTRN (+/+) and DMD (−/−) UTRN (−/−) mice.

When mice attained 4-6 weeks of age, male mice were castrated and treated as indicated in Table 28.

Compounds of formulas S-(III), S-(VI), and S-(V) were used at 10 mg per kg per day subcutaneously (mpk/day s.c.). Compound of formula S-(III) is the S-isomer of Compound III or (S)-N-(4-cyano-3-(trifluoromethyl)phenyl)-3-(4-cyanophenoxy)-2-hydroxy-2-methylpropanamide. Compound of formula S-(IV) is (S)-N-(3-chloro-4-cyano-phenyl)-3-(4-cyanophenoxy)-2-hydroxy-2-methylpropanamide. Compound of formula S-(V) is (S)-N-(4-cyano-3-(trifluoromethyl)phenyl)-3-(4-cyano-3-fluorophenoxy)-2-hydroxy-2-methylpropanamide. In FIGS. 38A-38C, ‘SARMs’ is cumulative data across groups 2, 3, and 4. In FIG. 39A, the labeling as ‘SARM’ indicates cumulative data across groups 2 and 4. One set of UTRN wildtype mice (i.e., the mdx model or DMD (−/−) UTRN (+/+) mice) were also used (i.e., groups 13-16) to evaluate the effect of S-(III) (and other SARMs) on Duchenne muscular dystrophy through UTRN up-regulation.

Weekly body weight, MRI measurements, and grip strengths were measured (body weight: biweekly; MRI scan: once every 2 weeks or once every week; and grip strength: Once every 2 weeks or once every week).

Groups 1-8 and 13-16 were sacrificed after 12 weeks of treatment and various tissues were excised, weighed, and stored appropriately for further analysis. At sacrifice, blood was collected for serum biochemical markers (ALT, AST, glucose, cholesterol, creatinine, creatine kinase, pyruvate, and others). Echocardiogram was performed in one set of knockout mice. As inflammation is considered as one of the primary pathogenic mechanisms, a serum inflammatory marker panel was evaluated. Organs (prostate, seminal vesicles, levator ani, soleus, gastrocnemious, heart, lungs, and liver) were weighed and stored for gene expression studies and histology. Levator ani, soleus, extensor digitorum longus (EDL), and gastrocnemious muscles were processed to measure the tension (if possible), histology and gene expression.

FIGS. 37A-37D show that DMD (−/−) UTRN (+/+) mice when treated with S-(III) demonstrated a significant increase in body weight (FIG. 37A), lean [muscle] mass (FIG. 37C), and grip strength (FIG. 37D), and also a decrease in fat mass (FIG. 37B).

FIGS. 38A-38C show that double knock out mice (DMD (−/−) UTRN (−/−)) when treated with vehicle significantly and rapidly lost their body weight, lean [muscle] mass, and grip strength. However, ‘SARMs’ (S-(III), S-(VI), and S-(V); data shown is cumulative across groups 1-4) delayed the deterioration of these measurements significantly. Further, ‘SARMs’ enhanced the ability of these mice to be ambulatory.

DMD (−/−) UTRN (−/−) male mice were castrated and treated with vehicle or a compound of this invention at 10 mpk s.c. The number of weeks the mice survived was recorded and expressed. The ‘SARM’ treated group combines the data for S-(III) and S-(V) treated animals together. Animals from the same litter are shown in FIG. 39B. FIGS. 39A (cumulative data for S-(III) and S-(V) and 39B (S-(III)) show that due to enhancement in body weight and lean [muscle] mass, the [castrated] DMD (−/−) UTRN (−/−) mice treated with the indicated compounds of the invention lived longer by approximately 40-50% compared to [castrated] vehicle-treated control mice from the same litter, suggesting the result is not due to genetic variation but drug efficacy. Cumulatively, this suggests that patients with Duchenne muscular dystrophy treated with S-(III) (or another SARM of this invention) are expected to not only benefit from improved growth and strength (e.g., improved physical function and quality of life such as longer ambulation) but also may live longer lives. A possible explanation for the survival benefit may be due, in part, to improved cardiac function.

FIGS. 40A and 40B and FIGS. 41A and 41B show that intact and castrated mdx mice, i.e., DMD (−/−) UTRN (+/+), were both effected by S-(III) treatment. The effects of S-(III) reported above for castrated mdx mice were also seen in intact mdx mice. E.g., S-(III) increased body weight (FIGS. 40A-40B) and lean mass (FIGS. 41A-41B) in castrated and intact mdx mice. This suggests that the therapeutic effects for Duchenne muscular dystrophy were not an artifact of the use of castrated animals to model the disease.
